What Is the Difference Between an Abstract and a Thesis Statement?

How to Write a Thesis & Introduction for a Critical Reflection Essay

College assignments, specifically the requirements when writing papers, can cause confusion for new students. Both forms of relaying information are utilized for different reasons but can be found within the same writing piece on occasion. Understanding the difference between two formats of information such as an abstract and thesis statement is important in professional writing at the college level. A strong thesis statement allows the reader to know what the stance of the writer is before reading through the full paper. An abstract allows the reader to understand at a glance what the full article is about.

An abstract is a short body of writing that is used to summarize a longer piece of writing. A dissertation for a doctoral program contains an abstract. The abstract information varies on the discipline that the writing addresses. In 1997, Philip Koopman from Carnegie Mellon University highlighted common considerations of an abstract to include the motivation, approach, problem statement, results and conclusion summarized into a brief document. The abstract is used to index the larger work or to simply describe the larger work. Abstracts allow researchers or readers to grasp the overall content of the full piece of writing within a paragraph or two.

Thesis Statement

A thesis statement is a claim by the writer that can be argued or disputed by others. The statement is typically one sentence but may contain more in rare circumstances. The sentence(s) will describe what the writer wants to specifically discuss about the central topic. The rule of thumb is not to state a fact but to take a position regarding the facts. Thesis statements appear in a variety of writing pieces from small writing assignments within a college course or a major submission for degree requirements.

Similarities

Although the thesis statement and abstract are different entities, they share a number of similarities. John December and Susan Katz who wrote for the Rensselaer Writing Center and the University of North Carolina highlight that both the abstract and thesis statement should be written after the significant body of the paper is complete. Both require significant research and consideration before formulation. It is also not uncommon to find both a thesis statement and abstract within the same writing piece.

Differences

The significant difference between an abstract and a thesis statement is the purpose behind each. While the abstract summarizes the important aspects of a complete writing piece, the thesis statement lays out only the position a writer is offering within the document. The abstract is longer in length and contains at least five factors regarding the writing it introduces. The thesis statement is short and contains one significant piece of information to inform the reader.

The Dissertation Abstract: 101

How to write a clear & concise abstract (with examples).

By:   Madeline Fink (MSc) Reviewed By: Derek Jansen (MBA)   | June 2020

So, you’ve (finally) finished your thesis or dissertation or thesis. Now it’s time to write up your abstract (sometimes also called the executive summary). If you’re here, chances are you’re not quite sure what you need to cover in this section, or how to go about writing it. Fear not – we’ll explain it all in plain language , step by step , with clear examples .

Overview: The Dissertation/Thesis Abstract

  • What exactly is a dissertation (or thesis) abstract
  • What’s the purpose and function of the abstract
  • Why is the abstract so important
  • How to write a high-quality dissertation abstract
  • Example/sample of a quality abstract
  • Quick tips to write a high-quality dissertation abstract

What is an abstract?

Simply put, the abstract in a dissertation or thesis is a short (but well structured) summary that outlines the most important points of your research (i.e. the key takeaways). The abstract is usually 1 paragraph or about 300-500 words long (about one page), but but this can vary between universities.

A quick note regarding terminology – strictly speaking, an abstract and an executive summary are two different things when it comes to academic publications. Typically, an abstract only states what the research will be about, but doesn’t explore the findings – whereas an executive summary covers both . However, in the context of a dissertation or thesis, the abstract usually covers both, providing a summary of the full project.

In terms of content, a good dissertation abstract usually covers the following points:

  • The purpose of the research (what’s it about and why’s that important)
  • The methodology (how you carried out the research)
  • The key research findings (what answers you found)
  • The implications of these findings (what these answers mean)

We’ll explain each of these in more detail a little later in this post. Buckle up.

A good abstract should detail the purpose, the methodology, the key findings and the limitations of the research study.

What’s the purpose of the abstract?

A dissertation abstract has two main functions:

The first purpose is to  inform potential readers  of the main idea of your research without them having to read your entire piece of work. Specifically, it needs to communicate what your research is about (what were you trying to find out) and what your findings were . When readers are deciding whether to read your dissertation or thesis, the abstract is the first part they’ll consider. 

The second purpose of the abstract is to  inform search engines and dissertation databases  as they index your dissertation or thesis. The keywords and phrases in your abstract (as well as your keyword list) will often be used by these search engines to categorize your work and make it accessible to users. 

Simply put, your abstract is your shopfront display window – it’s what passers-by (both human and digital) will look at before deciding to step inside. 

The abstract serves to inform both potential readers (people) and search engine bots of the contents of your research.

Why’s it so important?

The short answer – because most people don’t have time to read your full dissertation or thesis! Time is money, after all…

If you think back to when you undertook your literature review , you’ll quickly realise just how important abstracts are! Researchers reviewing the literature on any given topic face a mountain of reading, so they need to optimise their approach. A good dissertation abstract gives the reader a “TLDR” version of your work – it helps them decide whether to continue to read it in its entirety. So, your abstract, as your shopfront display window, needs to “sell” your research to time-poor readers.

You might be thinking, “but I don’t plan to publish my dissertation”. Even so, you still need to provide an impactful abstract for your markers. Your ability to concisely summarise your work is one of the things they’re assessing, so it’s vital to invest time and effort into crafting an enticing shop window.  

A good abstract also has an added purpose for grad students . As a freshly minted graduate, your dissertation or thesis is often your most significant professional accomplishment and highlights where your unique expertise lies. Potential employers who want to know about this expertise are likely to only read the abstract (as opposed to reading your entire document) – so it needs to be good!

Think about it this way – if your thesis or dissertation were a book, then the abstract would be the blurb on the back cover. For better or worse, readers will absolutely judge your book by its cover .

Even if you have no intentions to publish  your work, you still need to provide an impactful abstract for your markers.

How to write your abstract

As we touched on earlier, your abstract should cover four important aspects of your research: the purpose , methodology , findings , and implications . Therefore, the structure of your dissertation or thesis abstract needs to reflect these four essentials, in the same order.  Let’s take a closer look at each of them, step by step:

Step 1: Describe the purpose and value of your research

Here you need to concisely explain the purpose and value of your research. In other words, you need to explain what your research set out to discover and why that’s important. When stating the purpose of research, you need to clearly discuss the following:

  • What were your research aims and research questions ?
  • Why were these aims and questions important?

It’s essential to make this section extremely clear, concise and convincing . As the opening section, this is where you’ll “hook” your reader (marker) in and get them interested in your project. If you don’t put in the effort here, you’ll likely lose their interest.

Step 2: Briefly outline your study’s methodology

In this part of your abstract, you need to very briefly explain how you went about answering your research questions . In other words, what research design and methodology you adopted in your research. Some important questions to address here include:

  • Did you take a qualitative or quantitative approach ?
  • Who/what did your sample consist of?
  • How did you collect your data?
  • How did you analyse your data?

Simply put, this section needs to address the “ how ” of your research. It doesn’t need to be lengthy (this is just a summary, after all), but it should clearly address the four questions above.

Step 3: Present your key findings

Next, you need to briefly highlight the key findings . Your research likely produced a wealth of data and findings, so there may be a temptation to ramble here. However, this section is just about the key findings – in other words, the answers to the original questions that you set out to address.

Again, brevity and clarity are important here. You need to concisely present the most important findings for your reader.

Step 4: Describe the implications of your research

Have you ever found yourself reading through a large report, struggling to figure out what all the findings mean in terms of the bigger picture? Well, that’s the purpose of the implications section – to highlight the “so what?” of your research. 

In this part of your abstract, you should address the following questions:

  • What is the impact of your research findings on the industry /field investigated? In other words, what’s the impact on the “real world”. 
  • What is the impact of your findings on the existing body of knowledge ? For example, do they support the existing research?
  • What might your findings mean for future research conducted on your topic?

If you include these four essential ingredients in your dissertation abstract, you’ll be on headed in a good direction.

The purpose of the implications section is to highlight the "so what?" of your research. In other words, to highlight its value.

Example: Dissertation/thesis abstract

Here is an example of an abstract from a master’s thesis, with the purpose , methods , findings , and implications colour coded.

The U.S. citizenship application process is a legal and symbolic journey shaped by many cultural processes. This research project aims to bring to light the experiences of immigrants and citizenship applicants living in Dallas, Texas, to promote a better understanding of Dallas’ increasingly diverse population. Additionally, the purpose of this project is to provide insights to a specific client, the office of Dallas Welcoming Communities and Immigrant Affairs, about Dallas’ lawful permanent residents who are eligible for citizenship and their reasons for pursuing citizenship status . The data for this project was collected through observation at various citizenship workshops and community events, as well as through semi-structured interviews with 14 U.S. citizenship applicants . Reasons for applying for U.S. citizenship discussed in this project include a desire for membership in U.S. society, access to better educational and economic opportunities, improved ease of travel and the desire to vote. Barriers to the citizenship process discussed in this project include the amount of time one must dedicate to the application, lack of clear knowledge about the process and the financial cost of the application. Other themes include the effects of capital on applicant’s experience with the citizenship process, symbolic meanings of citizenship, transnationalism and ideas of deserving and undeserving surrounding the issues of residency and U.S. citizenship. These findings indicate the need for educational resources and mentorship for Dallas-area residents applying for U.S. citizenship, as well as a need for local government programs that foster a sense of community among citizenship applicants and their neighbours.

Practical tips for writing your abstract

When crafting the abstract for your dissertation or thesis, the most powerful technique you can use is to try and put yourself in the shoes of a potential reader. Assume the reader is not an expert in the field, but is interested in the research area. In other words, write for the intelligent layman, not for the seasoned topic expert. 

Start by trying to answer the question “why should I read this dissertation?”

Remember the WWHS.

Make sure you include the  what , why ,  how , and  so what  of your research in your abstract:

  • What you studied (who and where are included in this part)
  • Why the topic was important
  • How you designed your study (i.e. your research methodology)
  • So what were the big findings and implications of your research

Keep it simple.

Use terminology appropriate to your field of study, but don’t overload your abstract with big words and jargon that cloud the meaning and make your writing difficult to digest. A good abstract should appeal to all levels of potential readers and should be a (relatively) easy read. Remember, you need to write for the intelligent layman.

Be specific.

When writing your abstract, clearly outline your most important findings and insights and don’t worry about “giving away” too much about your research – there’s no need to withhold information. This is the one way your abstract is not like a blurb on the back of a book – the reader should be able to clearly understand the key takeaways of your thesis or dissertation after reading the abstract. Of course, if they then want more detail, they need to step into the restaurant and try out the menu.

Writing an Abstract for Your Research Paper

Definition and Purpose of Abstracts

An abstract is a short summary of your (published or unpublished) research paper, usually about a paragraph (c. 6-7 sentences, 150-250 words) long. A well-written abstract serves multiple purposes:

  • an abstract lets readers get the gist or essence of your paper or article quickly, in order to decide whether to read the full paper;
  • an abstract prepares readers to follow the detailed information, analyses, and arguments in your full paper;
  • and, later, an abstract helps readers remember key points from your paper.

It’s also worth remembering that search engines and bibliographic databases use abstracts, as well as the title, to identify key terms for indexing your published paper. So what you include in your abstract and in your title are crucial for helping other researchers find your paper or article.

If you are writing an abstract for a course paper, your professor may give you specific guidelines for what to include and how to organize your abstract. Similarly, academic journals often have specific requirements for abstracts. So in addition to following the advice on this page, you should be sure to look for and follow any guidelines from the course or journal you’re writing for.

The Contents of an Abstract

Abstracts contain most of the following kinds of information in brief form. The body of your paper will, of course, develop and explain these ideas much more fully. As you will see in the samples below, the proportion of your abstract that you devote to each kind of information—and the sequence of that information—will vary, depending on the nature and genre of the paper that you are summarizing in your abstract. And in some cases, some of this information is implied, rather than stated explicitly. The Publication Manual of the American Psychological Association , which is widely used in the social sciences, gives specific guidelines for what to include in the abstract for different kinds of papers—for empirical studies, literature reviews or meta-analyses, theoretical papers, methodological papers, and case studies.

Here are the typical kinds of information found in most abstracts:

  • the context or background information for your research; the general topic under study; the specific topic of your research
  • the central questions or statement of the problem your research addresses
  • what’s already known about this question, what previous research has done or shown
  • the main reason(s) , the exigency, the rationale , the goals for your research—Why is it important to address these questions? Are you, for example, examining a new topic? Why is that topic worth examining? Are you filling a gap in previous research? Applying new methods to take a fresh look at existing ideas or data? Resolving a dispute within the literature in your field? . . .
  • your research and/or analytical methods
  • your main findings , results , or arguments
  • the significance or implications of your findings or arguments.

Your abstract should be intelligible on its own, without a reader’s having to read your entire paper. And in an abstract, you usually do not cite references—most of your abstract will describe what you have studied in your research and what you have found and what you argue in your paper. In the body of your paper, you will cite the specific literature that informs your research.

When to Write Your Abstract

Although you might be tempted to write your abstract first because it will appear as the very first part of your paper, it’s a good idea to wait to write your abstract until after you’ve drafted your full paper, so that you know what you’re summarizing.

What follows are some sample abstracts in published papers or articles, all written by faculty at UW-Madison who come from a variety of disciplines. We have annotated these samples to help you see the work that these authors are doing within their abstracts.

Choosing Verb Tenses within Your Abstract

The social science sample (Sample 1) below uses the present tense to describe general facts and interpretations that have been and are currently true, including the prevailing explanation for the social phenomenon under study. That abstract also uses the present tense to describe the methods, the findings, the arguments, and the implications of the findings from their new research study. The authors use the past tense to describe previous research.

The humanities sample (Sample 2) below uses the past tense to describe completed events in the past (the texts created in the pulp fiction industry in the 1970s and 80s) and uses the present tense to describe what is happening in those texts, to explain the significance or meaning of those texts, and to describe the arguments presented in the article.

The science samples (Samples 3 and 4) below use the past tense to describe what previous research studies have done and the research the authors have conducted, the methods they have followed, and what they have found. In their rationale or justification for their research (what remains to be done), they use the present tense. They also use the present tense to introduce their study (in Sample 3, “Here we report . . .”) and to explain the significance of their study (In Sample 3, This reprogramming . . . “provides a scalable cell source for. . .”).

Reporting new findings about the reasons for increasing economic homogamy among spouses

Gonalons-Pons, Pilar, and Christine R. Schwartz. “Trends in Economic Homogamy: Changes in Assortative Mating or the Division of Labor in Marriage?” Demography , vol. 54, no. 3, 2017, pp. 985-1005.

“The growing economic resemblance of spouses has contributed to rising inequality by increasing the number of couples in which there are two high- or two low-earning partners. [Annotation for the previous sentence: The first sentence introduces the topic under study (the “economic resemblance of spouses”). This sentence also implies the question underlying this research study: what are the various causes—and the interrelationships among them—for this trend?] The dominant explanation for this trend is increased assortative mating. Previous research has primarily relied on cross-sectional data and thus has been unable to disentangle changes in assortative mating from changes in the division of spouses’ paid labor—a potentially key mechanism given the dramatic rise in wives’ labor supply. [Annotation for the previous two sentences: These next two sentences explain what previous research has demonstrated. By pointing out the limitations in the methods that were used in previous studies, they also provide a rationale for new research.] We use data from the Panel Study of Income Dynamics (PSID) to decompose the increase in the correlation between spouses’ earnings and its contribution to inequality between 1970 and 2013 into parts due to (a) changes in assortative mating, and (b) changes in the division of paid labor. [Annotation for the previous sentence: The data, research and analytical methods used in this new study.] Contrary to what has often been assumed, the rise of economic homogamy and its contribution to inequality is largely attributable to changes in the division of paid labor rather than changes in sorting on earnings or earnings potential. Our findings indicate that the rise of economic homogamy cannot be explained by hypotheses centered on meeting and matching opportunities, and they show where in this process inequality is generated and where it is not.” (p. 985) [Annotation for the previous two sentences: The major findings from and implications and significance of this study.]

Analyzing underground pulp fiction publications in Tanzania, this article makes an argument about the cultural significance of those publications

Emily Callaci. “Street Textuality: Socialism, Masculinity, and Urban Belonging in Tanzania’s Pulp Fiction Publishing Industry, 1975-1985.” Comparative Studies in Society and History , vol. 59, no. 1, 2017, pp. 183-210.

“From the mid-1970s through the mid-1980s, a network of young urban migrant men created an underground pulp fiction publishing industry in the city of Dar es Salaam. [Annotation for the previous sentence: The first sentence introduces the context for this research and announces the topic under study.] As texts that were produced in the underground economy of a city whose trajectory was increasingly charted outside of formalized planning and investment, these novellas reveal more than their narrative content alone. These texts were active components in the urban social worlds of the young men who produced them. They reveal a mode of urbanism otherwise obscured by narratives of decolonization, in which urban belonging was constituted less by national citizenship than by the construction of social networks, economic connections, and the crafting of reputations. This article argues that pulp fiction novellas of socialist era Dar es Salaam are artifacts of emergent forms of male sociability and mobility. In printing fictional stories about urban life on pilfered paper and ink, and distributing their texts through informal channels, these writers not only described urban communities, reputations, and networks, but also actually created them.” (p. 210) [Annotation for the previous sentences: The remaining sentences in this abstract interweave other essential information for an abstract for this article. The implied research questions: What do these texts mean? What is their historical and cultural significance, produced at this time, in this location, by these authors? The argument and the significance of this analysis in microcosm: these texts “reveal a mode or urbanism otherwise obscured . . .”; and “This article argues that pulp fiction novellas. . . .” This section also implies what previous historical research has obscured. And through the details in its argumentative claims, this section of the abstract implies the kinds of methods the author has used to interpret the novellas and the concepts under study (e.g., male sociability and mobility, urban communities, reputations, network. . . ).]

Reporting a new method for reprogramming adult mouse fibroblasts into induced cardiac progenitor cells

“Several studies have reported reprogramming of fibroblasts into induced cardiomyocytes; however, reprogramming into proliferative induced cardiac progenitor cells (iCPCs) remains to be accomplished. [Annotation for the previous sentence: The first sentence announces the topic under study, summarizes what’s already known or been accomplished in previous research, and signals the rationale and goals are for the new research and the problem that the new research solves: How can researchers reprogram fibroblasts into iCPCs?] Here we report that a combination of 11 or 5 cardiac factors along with canonical Wnt and JAK/STAT signaling reprogrammed adult mouse cardiac, lung, and tail tip fibroblasts into iCPCs. The iCPCs were cardiac mesoderm-restricted progenitors that could be expanded extensively while maintaining multipo-tency to differentiate into cardiomyocytes, smooth muscle cells, and endothelial cells in vitro. Moreover, iCPCs injected into the cardiac crescent of mouse embryos differentiated into cardiomyocytes. iCPCs transplanted into the post-myocardial infarction mouse heart improved survival and differentiated into cardiomyocytes, smooth muscle cells, and endothelial cells.

Sample Abstract 4, a Structured Abstract

Reporting results about the effectiveness of antibiotic therapy in managing acute bacterial sinusitis, from a rigorously controlled study

Note: This journal requires authors to organize their abstract into four specific sections, with strict word limits. Because the headings for this structured abstract are self-explanatory, we have chosen not to add annotations to this sample abstract.

Wald, Ellen R., David Nash, and Jens Eickhoff. “Effectiveness of Amoxicillin/Clavulanate Potassium in the Treatment of Acute Bacterial Sinusitis in Children.” Pediatrics , vol. 124, no. 1, 2009, pp. 9-15.

“OBJECTIVE: The role of antibiotic therapy in managing acute bacterial sinusitis (ABS) in children is controversial. The purpose of this study was to determine the effectiveness of high-dose amoxicillin/potassium clavulanate in the treatment of children diagnosed with ABS.

METHODS : This was a randomized, double-blind, placebo-controlled study. Children 1 to 10 years of age with a clinical presentation compatible with ABS were eligible for participation. Patients were stratified according to age (<6 or ≥6 years) and clinical severity and randomly assigned to receive either amoxicillin (90 mg/kg) with potassium clavulanate (6.4 mg/kg) or placebo. A symptom survey was performed on days 0, 1, 2, 3, 5, 7, 10, 20, and 30. Patients were examined on day 14. Children’s conditions were rated as cured, improved, or failed according to scoring rules.

RESULTS: Two thousand one hundred thirty-five children with respiratory complaints were screened for enrollment; 139 (6.5%) had ABS. Fifty-eight patients were enrolled, and 56 were randomly assigned. The mean age was 6630 months. Fifty (89%) patients presented with persistent symptoms, and 6 (11%) presented with nonpersistent symptoms. In 24 (43%) children, the illness was classified as mild, whereas in the remaining 32 (57%) children it was severe. Of the 28 children who received the antibiotic, 14 (50%) were cured, 4 (14%) were improved, 4(14%) experienced treatment failure, and 6 (21%) withdrew. Of the 28children who received placebo, 4 (14%) were cured, 5 (18%) improved, and 19 (68%) experienced treatment failure. Children receiving the antibiotic were more likely to be cured (50% vs 14%) and less likely to have treatment failure (14% vs 68%) than children receiving the placebo.

CONCLUSIONS : ABS is a common complication of viral upper respiratory infections. Amoxicillin/potassium clavulanate results in significantly more cures and fewer failures than placebo, according to parental report of time to resolution.” (9)

Writing for Social Media: A Guide for Academics

  • How to Write an Abstract for a Dissertation

Written by Hannah Slack

Every PhD student will have to write an abstract. Whether it’s for a conference paper , journal article or your thesis , the abstract is an important part for many academic activities. Although only a single short paragraph, writing one effectively takes practice.

This page will take you through what a dissertation abstract is, why it’s so important and how to write one.

On this page

What is an academic abstract.

An academic abstract is a short and concise summary of research . It should cover the aim or research question of your work, your methodology, results and the wider implications of your conclusions. All this needs to be covered in around 200-300 words .

One of the common mistakes people make when writing abstracts is not understanding their purpose. An abstract is not for the author, it’s for the reader . To summarise your research, as the person who knows it best, may seem easy. But to be able to communicate the complexities and importance of your work to someone else, likely outside of your field, can be difficult.

When will I need to write an academic abstract?

There are many different places that you’ll find abstracts. Some of the most common ones include:

  • Grant and funding applications
  • Journal articles
  • Conference applications
  • Conference proceedings

This guide primarily focuses on the dissertation abstract, which is the most common form of this kind of text.

What’s the difference between an abstract and an introduction?

The main differences between a PhD dissertation abstract and an introduction are the purpose and the length. An abstract is a short, paragraph-sized summary of the whole thesis, covering context, your research and results. Whereas an introduction should be much longer and only cover the context of your work. An introduction is designed to explain the background of your work and so will take up at least an entire page.

Why are abstracts important?

Abstracts are important because they are a quick and easy way to communicate your work. In many ways, academic abstracts are a promotional tool and so should be considered carefully.

For your thesis, it’s the first thing your examiners will read, forming their expectations for the rest of the dissertation.

In journal articles, their purpose is to convince the reader that they should read your article. If you’re applying for a conference, the abstract gives the organiser a taster of your paper so they can decide whether it’s suitable.

Effectively, your abstract is the first impression someone gets of your research and so it’s important to put your best foot forward.

How to write a PhD abstract

How you write a dissertation abstract will largely depend on what it’s for. For a PhD dissertation or journal article, you should have already written up the research which the abstract will summarise. You should focus on making sure your summary is an honest representation of the larger written work. However, for a conference application it’s likely you won’t yet have written the paper. In this instance, the abstract might focus more on the broader themes you intend to comment on and your methodology.

Whatever the intended purpose, all abstracts should broadly follow the same structure. To help you, we’ve put together a template to make sure you include all the important points.

PhD abstract format

Because a lot of information needs to be packed into a short paragraph, an abstract is easier to write when you break it down into the key elements. For a first draft, spend a few minutes on each of the six steps, only writing down one or two sentences.

  • Rationale – Ask yourself why you are researching the topic and what is the context for your work. Here you should communicate the purpose of your study within the wider field.
  • Research question – Now you should specify what the exact goal of this piece of research is. What question are you providing the answer for?
  • Evidence and methods – After discussing the broader purpose of your work you now need to let the reader know what you have actually done. Try to summarise your methods and evidence with a few keywords to keep if brief. Some examples include qualitative, quantitative, archival or experimental.
  • Results – Here, you should summarise your outcomes and highlight what is new or significant about your findings.
  • Conclusion – The conclusion should relate back to your rationale and research question. Ask yourself, ‘what do the results mean?’
  • Implications and applications – Lastly, the reader needs to know why your results are important to the field. You need to specify what is significant about this work and how it can be useful.

Once you have your framework it can be edited for a more natural flow. You may find that some points naturally merge into one sentence and others need some elaboration. But remember, the abstract must be short and concise so don’t be tempted to extend areas unnecessarily. Once you have a draft that you are happy with, consider asking for feedback from other PhD students or your supervisor.

How to Write an Abstract for Your Thesis or Dissertation What is an Abstract? The abstract is an important component of your thesis. Presented at the beginning of the thesis, it is likely the first substantive description of your work read by an external examiner. You should view it as an opportunity to set accurate expectations. The abstract is a summary of the whole thesis. It presents all the major elements of your work in a highly condensed form. An abstract often functions, together with the thesis title, as a stand-alone text. Abstracts appear, absent the full text of the thesis, in bibliographic indexes such as PsycInfo. They may also be presented in announcements of the thesis examination. Most readers who encounter your abstract in a bibliographic database or receive an email announcing your research presentation will never retrieve the full text or attend the presentation. An abstract is not merely an introduction in the sense of a preface, preamble, or advance organizer that prepares the reader for the thesis. In addition to that function, it must be capable of substituting for the whole thesis when there is insufficient time and space for the full text. Size and Structure Currently, the maximum sizes for abstracts submitted to Canada's National Archive are 150 words (Masters thesis) and 350 words (Doctoral dissertation). To preserve visual coherence, you may wish to limit the abstract for your doctoral dissertation to one double-spaced page, about 280 words. The structure of the abstract should mirror the structure of the whole thesis, and should represent all its major elements. For example, if your thesis has five chapters (introduction, literature review, methodology, results, conclusion), there should be one or more sentences assigned to summarize each chapter. Clearly Specify Your Research Questions As in the thesis itself, your research questions are critical in ensuring that the abstract is coherent and logically structured. They form the skeleton to which other elements adhere. They should be presented near the beginning of the abstract. There is only room for one to three questions. If there are more than three major research questions in your thesis, you should consider restructuring them by reducing some to subsidiary status. Don't Forget the Results The most common error in abstracts is failure to present results. The primary function of your thesis (and by extension your abstract) is not to tell readers what you did, it is to tell them what you discovered. Other information, such as the account of your research methods, is needed mainly to back the claims you make about your results. Approximately the last half of the abstract should be dedicated to summarizing and interpreting your results. Updated 2008.09.11 © John C. Nesbit

Intro Vs Abstract – Are They The Same?

Scholarly writing serves as a cornerstone for the dissemination of knowledge and the exploration of new ideas. Two crucial elements that play a pivotal role in framing the structure of academic papers are the introduction and abstract. While often used interchangeably, these components serve distinct purposes, each contributing to a scholarly work’s overall coherence and effectiveness.

Table of Contents

Understanding The Introduction

The introduction serves as the gateway to a scholarly work, setting the stage for what lies ahead. It is not merely a perfunctory beginning but a strategic piece that aims to engage readers, provide context, and establish the groundwork for the research to follow. The primary functions of an introduction can be delineated into several key aspects.

Contextualization

The introduction contextualizes the research by presenting the broader field of study. It provides a backdrop against which the specific research question or problem statement can be understood.

This involves reviewing relevant literature, highlighting gaps in existing knowledge, and justifying the need for the current study.

Statement Of The Problem Or Research Question

One of the critical elements of an introduction is the formulation of a clear and concise research question or problem statement. This sets the trajectory for the entire paper, guiding readers on what to expect and why the study is significant.

Objectives And Scope

The introduction outlines the objectives of the research and delineates the scope of the study. This helps readers understand the boundaries within which the research is conducted and what specific aspects will be addressed.

Hypotheses Or Research Hypothesis

In scientific research, the introduction may present hypotheses that the study aims to test. These hypotheses are formulated based on existing knowledge and are critical for guiding the research methodology and analysis.

Thesis Statement

In some academic disciplines, particularly in humanities and social sciences, the introduction may encapsulate the thesis statement —a concise summary of the main argument or position taken in the paper.

Understanding The Abstract

While the introduction sets the stage, the abstract serves as a concise summary that encapsulates the entire research paper. Positioned at the beginning of the paper, the abstract acts as a standalone piece, providing readers with a snapshot of the research without requiring them to delve into the full text. The abstract has its own distinct set of functions and characteristics.

Summary Of Key Elements

The abstract encapsulates the essential elements of the research, including the research question, methodology, key findings, and conclusions. It serves as a condensed version of the entire paper, offering readers a quick overview.

Conciseness And Clarity

Unlike the introduction, the abstract is highly condensed and should be succinct. It demands clarity and precision in conveying the main points of the research without unnecessary details.

A well-crafted abstract can stand alone, providing readers with a clear understanding of the study even if they choose not to read the full paper.

Keywords And Indexing

Abstracts often include keywords that are relevant to the research. These keywords are essential for indexing and categorizing the paper in databases, making it easier for researchers to locate relevant literature.

No Citations Or References

Unlike the introduction, the abstract typically does not include citations or references in APA or MLA to other works. It is a self-contained unit that focuses solely on summarizing the research conducted in the paper.

Structural Alignment

The abstract should mirror the structure of the paper, summarizing each section in a logical sequence. It typically includes brief statements about the introduction, methodology, results, and conclusion.

What Is The Difference Between Intro Vs Abstract

While the introduction and abstract share the common goal of providing readers with a roadmap to the research, they differ significantly in their depth, scope, and functions. Understanding these distinctions is crucial for crafting a well-rounded and impactful research paper.

Establishes context, presents the research question, and justifies the study’s significance.Provides a concise summary of the entire paper, encapsulating key elements independently.
Background, context, literature review, research question, objectives, scope, and sometimes a thesis statement.Briefly covers the research question, methodology, key findings, and conclusions.
Relatively longer, comprising several paragraphs.Short and succinct, typically a standalone paragraph or section.
Includes citations and references to relevant literature.Generally avoids citations, presenting a self-contained summary.
Invites readers into the research narrative, providing a smooth transition to subsequent sections.Should be easily comprehensible on its own, allowing quick assessment of the paper’s relevance.
Follows the abstract and precedes the main body of the paper.Precedes the introduction, positioned at the beginning of the paper for quick reference.
Sets the stage, provides context, and guides readers into the research narrative.Serves as a standalone summary, offering a quick overview of the entire paper.
Does not typically include specific keywords.May include keywords relevant to the research for indexing purposes.
More detailed, covering various aspects of the study.Condenses key elements, focusing on the main points without delving into excessive detail.

While an abstract is a tightrope walker, restricted to a concise space, the introduction enjoys the freedom of expansiveness. It can stretch across paragraphs, weaving a tapestry of context and intrigue.

An abstract concentrates on the “what” and the “how” – highlighting the research question, methodology, and results. The introduction delves deeper, exploring the “why” – establishing the importance of your work and engaging the reader emotionally.

An abstract primarily caters to specialists and peer reviewers and needs technical accuracy and jargon. The introduction speaks to a broader audience, using accessible language and captivating storytelling to pique their interest.

An abstract follows a rigid format, typically outlining the research question, methodology, results, and conclusion. The introduction offers greater flexibility, allowing for creative storytelling and engaging transitions.

Depth Of Detail

The introduction provides a comprehensive overview of the background, context, and rationale for the study. It delves into existing literature, establishes the research question, and outlines the objectives. In contrast, the abstract is a condensed summary, offering a snapshot of the entire paper without the depth of detail found in the introduction.

Inclusion Of Citations

The introduction extensively cites relevant literature reviews to provide a foundation for the research. It establishes the scholarly context and justifies the study’s significance. On the other hand, the abstract typically avoids citations and focuses on presenting the research’s key elements without reference to external works.

Readability And Accessibility

The introduction is designed to be read sequentially, guiding readers from the general to the specific. It is an integral part of the paper’s narrative, contributing to the overall flow. In contrast, the abstract is a standalone piece that should be easily understandable on its own. It serves as a quick reference for researchers scanning multiple papers to determine their relevance.

Function Within The Paper

The introduction serves as a foundation for the entire paper, providing the necessary context for readers to understand the study’s purpose and significance.

It invites readers into the research narrative, guiding them through the subsequent sections. On the other hand, the abstract is a succinct summary that allows readers to quickly assess the paper’s content, methodology, and findings without delving into the full text.

Strategies For Crafting Effective Introductions And Abstracts

Crafting compelling introductions and abstracts is a skill that evolves with practice and a nuanced understanding of the research process. Here are some strategies to enhance the effectiveness of these key components:

Clarity And Precision

Both the introduction and abstract benefit from clarity and precision. Use clear language to convey ideas and avoid unnecessary jargon. Ensure that each sentence serves a specific purpose and contributes to the overall coherence of the text.

Engaging The Reader

The introduction should engage the reader from the outset. Consider using anecdotes, thought-provoking questions, or relevant statistics to capture attention. Create a narrative flow that seamlessly leads readers from the general context to the specific research question.

Conciseness In The Abstract

Given its condensed nature, the abstract requires a careful selection of words to convey maximum information in a limited space. Avoid unnecessary details and focus on presenting the core elements of the research. Aim for brevity without sacrificing clarity.

Both the introduction and abstract should align with the overall structure of the paper. Ensure that the abstract provides a coherent summary of each section, mirroring the paper’s organization. Similarly, the introduction should seamlessly transition into subsequent sections.

Highlighting Significance

Clearly articulate the significance of the research in both the introduction and abstract. Explain why the study is relevant, what gaps it addresses, and how

Proofreading And Editing

Thoroughly proofread and edited both the introduction and abstract to eliminate grammatical errors, typos, and inconsistencies. Pay attention to the overall flow of the text, ensuring that ideas are presented logically and coherently.

Importance of a Good Abstract

Sometimes your professor will ask you to include an abstract, or general summary of your work, with your research paper. The abstract allows you to elaborate upon each major aspect of the paper and helps readers decide whether they want to read the rest of the paper. Therefore, enough key information [e.g., summary results, observations, trends, etc.] must be included to make the abstract useful to someone who may want to examine your work.

How do you know when you have enough information in your abstract? A simple rule-of-thumb is to imagine that you are another researcher doing a similar study. Then ask yourself: if your abstract was the only part of the paper you could access, would you be happy with the amount of information presented there? Does it tell the whole story about your study? If the answer is "no" then the abstract likely needs to be revised.

Structure and Writing Style

I.  Types of Abstracts

To begin, you need to determine which type of abstract you should include with your paper. There are four general types.

Critical Abstract A critical abstract provides, in addition to describing main findings and information, a judgment or comment about the study’s validity, reliability, or completeness. The researcher evaluates the paper and often compares it with other works on the same subject. Critical abstracts are generally 400-500 words in length due to the additional interpretive commentary. These types of abstracts are used infrequently.

Descriptive Abstract A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarized. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less. Informative Abstract The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.

Highlight Abstract A highlight abstract is specifically written to attract the reader’s attention to the study. No pretense is made of there being either a balanced or complete picture of the paper and, in fact, incomplete and leading remarks may be used to spark the reader’s interest. In that a highlight abstract cannot stand independent of its associated article, it is not a true abstract and, therefore, rarely used in academic writing.

II.  Writing Style

Use the active voice when possible , but note that much of your abstract may require passive sentence constructions. Regardless, write your abstract using concise, but complete, sentences. Get to the point quickly and always use the past tense because you are reporting on a study that has been completed.

Abstracts should be formatted as a single paragraph in a block format and with no paragraph indentations. In most cases, the abstract page immediately follows the title page. Do not number the page. Rules set forth in writing manual vary but, in general, you should center the word "Abstract" at the top of the page with double spacing between the heading and the abstract. The final sentences of an abstract concisely summarize your study’s conclusions, implications, or applications to practice and, if appropriate, can be followed by a statement about the need for additional research revealed from the findings.

Composing Your Abstract

Although it is the first section of your paper, the abstract should be written last since it will summarize the contents of your entire paper. A good strategy to begin composing your abstract is to take whole sentences or key phrases from each section of the paper and put them in a sequence that summarizes the contents. Then revise or add phrases or words to make the narrative flow clearly and smoothly. A useful strategy is to avoid using conjunctions [ e.g. and, but, if] that connect long clauses or sentences and, instead, write short, concise sentences . Note that statistical findings should be reported parenthetically [i.e., written in parentheses].

Before handing in your final paper, check to make sure that the information in the abstract completely agrees with what you have written in the paper. Think of the abstract as a sequential set of complete sentences describing the most crucial information using the fewest necessary words. The abstract SHOULD NOT contain:

  • A catchy introductory phrase, provocative quote, or other device to grab the reader's attention,
  • Lengthy background or contextual information,
  • Redundant phrases, unnecessary adverbs and adjectives, and repetitive information;
  • Acronyms or abbreviations,
  • References to other literature [say something like, "current research shows that..." or "studies have indicated..."],
  • Using ellipticals [i.e., ending with "..."] or incomplete sentences,
  • Jargon or terms that may be confusing to the reader,
  • Citations to other works, and
  • Any sort of image, illustration, figure, or table, or references to them.

Writing Tip

Never Cite Just the Abstract!

Citing to just a journal article's abstract does not confirm for the reader that you have conducted a thorough or reliable review of the literature. If the full-text is not available, go to the USC Libraries main page and enter the title of the article [NOT the title of the journal]. If the Libraries have a subscription to the journal, the article should appear with a link to the full-text or to the journal publisher page where you can get the article. If the article does not appear, try searching Google Scholar using the link on the USC Libraries main page [scroll down under the heading Quick Links]. If you still can't find the article after doing this, contact a librarian or you can request it from our free i nterlibrary loan and document delivery service .

An abstract is a summary of a longer written document. It is written with the same organization as the original document, usually without “review” or comment. Abstract lengths vary by discipline and purpose of the project; generally, they are 50-100 words for a short paper and 150-200 for a longer one. Abstracts are typically placed prior to the manuscript. Abstracts fall into two categories: indicative and informative.

The  indicative  abstract covers a less structured document (like a book, essay or editorial). It helps readers to understand the focus, arguments and conclusions of the larger document so that they can determine whether to read it more thoroughly.

An  informative  abstract is used for more strictly structured documents (like scientific experiments or investigations) and includes the elements of the original research report: its objective, methods, results, and conclusions.

Whichever type of abstract you write, it should be able to stand alone as a statement separate from the larger document.

Components of an Abstract

Abstracts, at heart, are decision-making documents. Based on the abstract, readers decide whether to read your article, support your proposal, grant your funding, or accept you to a conference. To write a successful abstract, you need to include these three components:  Context ,  Problem , and  Response  (CPR).

By definition, context is essentially what surrounds a thing. In other words, in order to understand a snippet of conversation, we often ask, “He said that in what context?” When we provide context for our readers, we are establishing a comfortable common ground, a shared understanding that provides an entry point into the larger or more specific ideas of our project. Common ground might take the form of a shared belief, a kind of truism, or a basic principle of the field. Frequently this takes the form of a brief survey of the field or an overview of a current situation. This might include what those in the discipline already know to be true, a point of conventional wisdom, something we’ve all seen and heard, a primary text, a case study, or an anecdote of some kind. 

The problem is essentially establishing a deficit. A deficit in this sense refers to a gap in knowledge or what might be misunderstood or overlooked. The problem is what our research question or project is trying to solve. This might be, for example, a practical question (how can we best distribute H1N1 vaccine?) or it can be a theoretical or conceptual question (to what degree is marital behavior determined by intergenerational influences?). As researchers, we begin with the problem, but often by the time we are ready to write our abstracts, introductions, or proposals, the problem has moved into the background, obscured by the details of our work. However, in terms of meeting the reader’s needs, the problem is an essential and necessary feature. The reader’s level of investment, and thus the grade, the acceptance, the funding for your project hinges upon how successfully you articulate the problem. 

This is generally your summary or description of your paper or project, which you position in dialogue with the problem as you’ve established it. Depending on the nature of your project, in your response you might explicitly state your main point or thesis, or you might present your hypothesis and generalize your results. In addition, research that relies on primary data often includes an abbreviated description of the methodology used. 

The ABCs of a Good Abstract

  • Accuracy:  Include only information included in the original document.
  • Brevity:  Get straight to the point, use precise language, and do not include superfluous adjectives.
  • Clarity:  Do not use unnecessary technical jargon, colloquialisms or obscure vocabulary and detail and always explain any acronyms.

Abstracts are challenging because they require decisions about what constitutes that essence of a document full of important information. Here are some tips to help you:

  • Write the final version of your abstract after your paper is completed so the organization and development of the two documents match.
  • Begin with a topic sentence: what is this paper about?
  • Use an outline to confirm that you are summarizing the most important information.
  • Incorporate keywords for electronic retrieval into the text. (They may also be listed at the end of the abstract text.) Bibliographic references and graphics are typically excluded from an abstract.

Keep your readers in mind as you develop the abstract:

  • Assume that they are generally familiar with the information being abstracted but are interested in evaluating the usefulness of the entire document for their research.
  • Write in a concise and readable style so that they can read through the abstract quickly to ascertain the essence of the larger document.
  • Provide information in each sentence; for example, if it is important enough to include, “a cost was given,” it is appropriate to give the specifics: “The cost was $5.25 per gallon.”

Variation Among Isolates of Fusarium Circinatum in Tolerance of the Anti-fungal Metabolite   BOA

Amir Begovic

Fusarium circinatum is a fungal pathogen responsible for a disease affecting pines known as pitch canker. Although this is what F. circinatum is notorious for, recent work has shown that this fungus also can colonize grasses. However, the importance of grasses as a resource in the life history of F. circinatum is unknown. To learn more about how well adapted F. circinatum is to exploitation of grass hosts, the present study was undertaken to determine how well this fungus can tolerate anti-fungal compounds produced by corn, a member of the grass family. To this end, plates of PDA (potato dextrose agar) were amended with various concentrations of BOA (2-benzoxazolinone), and inoculated with a colonized agar plug of F. circinatum. All tested strains failed to grow at concentrations of 0.75 and 1.0 mg of BOA per ml of medium. Colonized plugs transferred from plates containing BOA to PDA without BOA did not grow, indicating the fungus was killed by exposure to this anti-fungal compound. The same strains were able to survive exposure to 0.5 mg of BOA per ml, although growth was strongly inhibited. The next step will be to test for heritable variation in tolerance of BOA in F. circinatum. (197 words)

Connecting the U.S. Media: A Network Analysis of Mutual Fund Ownership in Communication Corporations

Grace A. Benefield

Social scientists have long been interested in the ever increasing concentration and effects of computer, telecommunication and media corporations, such as Google, Apple and Verizon. By gathering statistics on mutual fund and individual stock owners, the study compares the proportion of institutional investment across communication corporations, which are service or technology corporations responsible for the exchange of information. The research incorporates network analysis software to identify outliers and central players in this web of media owners. The study seeks to measure centrality as a connection between two companies and their investors' similar interest investments, such as a similarity in size, expectations for growth, company values, or industrial interests. Surprisingly, the study finds that market capitalization did not result in centrality, such as IBM's peripheral status. The results find that smaller telecommunications companies, such as Sprint and Comcast, share a large portion of the same mutual funds. In contrast, other industries appear to have intermixed and varietal institutional owners. There are also indications of mutual fund interest groupings based on geography, as in west coast companies Disney, HP, and Qualcomm. Further research is needed to compare the individual stock owners who control large interests in various companies. (196 words)

Writing an abstract - a six point checklist (with samples)

Posted in: abstract , dissertations

are abstract and thesis the same

The abstract is a vital part of any research paper. It is the shop front for your work, and the first stop for your reader. It should provide a clear and succinct summary of your study, and encourage your readers to read more. An effective abstract, therefore should answer the following questions:

  • Why did you do this study or project?
  • What did you do and how?
  • What did you find?
  • What do your findings mean?

So here's our run down of the key elements of a well-written abstract.

  • Size - A succinct and well written abstract should be between approximately 100- 250 words.
  • Background - An effective abstract usually includes some scene-setting information which might include what is already known about the subject, related to the paper in question (a few short sentences).
  • Purpose  - The abstract should also set out the purpose of your research, in other words, what is not known about the subject and hence what the study intended to examine (or what the paper seeks to present).
  • Methods - The methods section should contain enough information to enable the reader to understand what was done, and how. It should include brief details of the research design, sample size, duration of study, and so on.
  • Results - The results section is the most important part of the abstract. This is because readers who skim an abstract do so to learn about the findings of the study. The results section should therefore contain as much detail about the findings as the journal word count permits.
  • Conclusion - This section should contain the most important take-home message of the study, expressed in a few precisely worded sentences. Usually, the finding highlighted here relates to the primary outcomes of the study. However, other important or unexpected findings should also be mentioned. It is also customary, but not essential, to express an opinion about the theoretical or practical implications of the findings, or the importance of their findings for the field. Thus, the conclusions may contain three elements:
  • The primary take-home message.
  • Any additional findings of importance.
  • Implications for future studies.

And finally...  A word on abstract types and styles

Abstract types can differ according to subject discipline. You need to determine therefore which type of abstract you should include with your paper. Here are two of the most common types with examples.

Informative Abstract

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.

Descriptive Abstract A descriptive abstract indicates the type of information found in the work. It makes no judgements about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarised. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less.

Abstract vs Introduction – Differences Explained

Picture of Dr Harry Hothi

  • By Dr Harry Hothi
  • August 29, 2020

Abstract vs Introduction

Any academic write up of a research study or project will require the inclusion of an abstract and introduction. If you pick up any example of a research paper for a journal, dissertation for a Masters degree or a PhD thesis, you’ll see the abstract, followed by the introduction. At first glance you’ll notice that the abstract is much shorter in length, typically a quarter or third of a page of A4. The introduction on the other hand is longer, taking up at least an entire page of writing.

Beyond the length, what are the differences in the content of the two sections? In short, the abstract is a summary of the entire study, describing the context, research aim, methods, results and key conclusions. The introduction gives more detail on the background of the subject area, the motivation for the study and states the aims and objectives.

Read on to learn more.

What is an Abstract?

The main purpose of an abstract is to succinctly give the reader an overview of why the study was needed, what the purpose of the project was, the research question, the key materials and methods that were used, the main results and what conclusions were drawn from this. Many abstracts also conclude with a sentence on the significance or impact of the research. These are sometimes also referred to as an executive summary.

The reader should have an understanding of the paper topic and what the study was about from the abstract alone. He or she can then decide if they want to read the paper or thesis in more detail.

Abstracts are particularly useful for researchers performing a literature review, which involves critically evaluating a large number of papers. Reading the abstract enables them to quickly ascertain the key points of a paper, helping them identify which ones to read in full.

Abstracts are also very important for learning more about the work performed in papers that are hidden behind academic journal paywalls (i.e. those that are not open access). Abstracts are always made freely available, allowing a researcher to understand the context and main point of the work and then decide if it’s worth paying to read the entire paper. These are sometimes referred to as the ‘de facto introduction’ to the research work as it’s usually the first section people read about your study, after the title page.

How do you Write an Abstract?

The majority of academic journals place a limit of 250 words on the length of the abstract in papers submitted to them. They do this to ensure you give a quick overview of only the most important information from your study, helping the reader decide if they want to read the whole paper too. Make sure you double check the specific requirements of your target journal before you start writing.

Universities or other academic institutions often allow up to 500 words for an abstract written for a doctoral thesis.

Abstracts can be either structured or unstructured in the way they are formatted. A structured abstract contains separate headings to guide the reader through the study. Virtually all STEM journals will require this format be used for a researcharticle. The exact names used for each heading can differ but generally there are defined as:

  • Background. This is also sometimes called the Introduction. This section should give an overview of what is currently known about the research topic and what the gap in knowledge is. The reader should understand the problem your research will address; i.e. what was your study needed. Don’t include any references or citations in the abstract.
  • Aim and Objective. Give a brief explanation of what the study intended to achieve and state the research question or questions that you proposed. Some authors also include the hypothesis here too.
  • Materials and Methods. Use the methods section to describe what you investigated, what the study design was and how you carried it out.
  • Results. Give an overview of your key findings.
  • Discussion and Conclusion. Some journals may ask for these two terms to be used as separated headings. These sections explain why you may have obtained the results that you did, what this means and what the significance or impact of this might be.

An informative abstract should provide a concise summary of all the important points in your research project, including what the central question relating to the subject matter was. Make it interesting to read too; this may be the difference between your abstract being accepted or rejected if you decide to submit it to an upcoming conference. Reviewers for large conferences often have to read hundreds of abstracts so make sure yours stands out by being easy to read and follow.

It’s less common that you’ll be asked to write an unstructured abstract. If you are, however, be aware that the key difference is that an unstructured abstract does not include separate headings. The flow of the abstract text should still follow the 5 points listed above but they should all be written within one long paragraph.

What is the Introduction?

The introduction section is the first main written work presented after the abstract in your paper manuscript or thesis. In a research paper, the introduction will be followed by a section on the materials and methods. In thesis writing, the introduction will be followed by the literature review .

The main aim of introduction writing is to give the reader more detail on the background information of the study. It should include a brief description of the key current knowledge that exists based on the work presented in previous literature and where the gaps in knowledge are. The introduction should convey why your research was needed in order to add new understanding to your subject area. Make sure that you reference all the publications that you refer to.

When writing an introduction for a scientific paper you should also include the aim of your study and the research objectives/questions. If relevant, also include your hypothesis or (null hypothesis).

How do you Structure the Introduction?

The general rule of thumb for a research paper is to use size 12 Times New Roman font, double spaced. Write four separate paragraphs which together are no longer than one page in length. Structure the four paragraphs as follows:

  • Set the context of the research study, giving background information about the subject area.
  • Describe what is currently know from previously published work and what is poorly understood – i.e. the research gap.
  • Explain how addressing this gap in knowledge is important for your research field – i.e. why this study is needed.
  • Give a broad overview of the aims, objectives and hypothesis of the study.

You should not describe the research method used in this section nor any results and conclusions.

You should be clear now on what the differences between an abstract vs introduction are. The best way to improve your academic writing skills for these are to read other examples from other  research articles and start writing!

In a thesis, which comes first - Abstract or Acknowledgements?

I am writing my masters thesis now. I saw some theses with the acknowledgement chapter after the abstract, in other cases it's the other way around.

I think the acknowledgement chapter is not related to the scientific work in the thesis, and thus should not be put between the abstract and the introduction. An abstract could be nice in the beginning if we're looking at a paper for example, but for a thesis (usually >80 pages) the reader would have to turn the pages anyway.

  • acknowledgement

You should check the guidelines from your university. I'd assume that they would have requirements for the order. If not, I always prefer the acknowledgements should come first, that way the non-scientific stuff is out of the way.

  • 1 Highly country dependent. In Germany, at least at my University, we had 0 (that is, literally zero) requirements, nor guidelines. –  Konrad Rudolph Commented Jun 18, 2012 at 9:15
  • @KonradRudolph lucky man. –  Zenon Commented Jun 20, 2012 at 14:46
  • 1 @Zenon No guidelines is not necessarily lucky, because you are still judged on your choices. –  user781 Commented Jun 22, 2012 at 12:37
  • 6 Just to illustrate how strange requirements can get, my doctoral thesis had to have the abstract first. I don't just mean before the acknowledgements, but before the title page. –  Luke Mathieson Commented Oct 8, 2012 at 10:43

Actually, under normal circumstances, I would expect the abstract to be as close to the front of a thesis as possible. The reason for this is to make the job of cataloging and searching easier. Abstracts of theses are indexed by services such as ProQuest , and having to wade through additional pages of material makes their work harder.

That said, scientifics is correct in that you should follow whatever regulations your university has. But in general, in the absence of such guidelines, I would put the abstract before the acknowledgments—readers want to know as soon as possible if they should bother to read the rest of your thesis. Burying it after the front matter makes it less likely for them to invest the time.

aeismail's user avatar

Just adding my two cents: around me, people commonly print out and bind their thesis in such a way that the one-page abstract is on the back cover . I think it makes a lot of sense, and allows one to get an idea of what the thesis is about without flipping pages (literally).

F'x's user avatar

I would prefer to put acknowledgement before the Abstract so that I will be done with the preliminaries first, so that when one reads Abstract he will have started looking at the actual content. To me acknowledgement coming between the Abstract and the introduction is a disruption. But the guidelines of the University are to be followed.

Thesis: Vasectomy: Goals, Practices, and Effects

Editor's note:

Cole Nichols defended his Barrett Honors College thesis entitled, "Vasectomy: Goals, Practices, and Effects" in Spring 2023 in front of committee members Jane Maienschein and Dina Ziganshina.  https://keep.lib.asu.edu/items/184626

Vasectomy is one of few widely available methods of contraception for people with male reproductive systems aside from condoms, abstinence, and the withdrawal method, and it is the only one of those options that can be permanent (Amory 2016). The procedure’s prominence has led me to investigate the history of vasectomy and particularly the evolution in vasectomy technique over time. Since its introduction in the late nineteenth century, the procedure has had a variety of impacts on many people across the world. In this research project, I have sought to analyze what the technical evolution of vasectomy reveals about the changing priorities of the medical systems that use it. In particular, I point to ways the eugenics movement’s attempts to control individual reproduction have led to both vasectomy’s efficacy and its restrictiveness.

Frequently asked questions

Where does the abstract go in a thesis or dissertation.

The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

Frequently asked questions: Dissertation

Dissertation word counts vary widely across different fields, institutions, and levels of education:

  • An undergraduate dissertation is typically 8,000–15,000 words
  • A master’s dissertation is typically 12,000–50,000 words
  • A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

A dissertation prospectus or proposal describes what or who you plan to research for your dissertation. It delves into why, when, where, and how you will do your research, as well as helps you choose a type of research to pursue. You should also determine whether you plan to pursue qualitative or quantitative methods and what your research design will look like.

It should outline all of the decisions you have taken about your project, from your dissertation topic to your hypotheses and research objectives , ready to be approved by your supervisor or committee.

Note that some departments require a defense component, where you present your prospectus to your committee orally.

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

  • Plan to attend graduate school soon
  • Have a particular topic you’d like to study more in-depth
  • Are considering a career in research
  • Would like a capstone experience to tie up your academic experience

The conclusion of your thesis or dissertation should include the following:

  • A restatement of your research question
  • A summary of your key arguments and/or results
  • A short discussion of the implications of your research

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

For a stronger dissertation conclusion , avoid including:

  • Important evidence or analysis that wasn’t mentioned in the discussion section and results section
  • Generic concluding phrases (e.g. “In conclusion …”)
  • Weak statements that undermine your argument (e.g., “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

While it may be tempting to present new arguments or evidence in your thesis or disseration conclusion , especially if you have a particularly striking argument you’d like to finish your analysis with, you shouldn’t. Theses and dissertations follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the discussion section and results section .) The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

A theoretical framework can sometimes be integrated into a  literature review chapter , but it can also be included as its own chapter or section in your dissertation . As a rule of thumb, if your research involves dealing with a lot of complex theories, it’s a good idea to include a separate theoretical framework chapter.

A literature review and a theoretical framework are not the same thing and cannot be used interchangeably. While a theoretical framework describes the theoretical underpinnings of your work, a literature review critically evaluates existing research relating to your topic. You’ll likely need both in your dissertation .

While a theoretical framework describes the theoretical underpinnings of your work based on existing research, a conceptual framework allows you to draw your own conclusions, mapping out the variables you may use in your study and the interplay between them.

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

  • Your anticipated title
  • Your abstract
  • Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

In most styles, the title page is used purely to provide information and doesn’t include any images. Ask your supervisor if you are allowed to include an image on the title page before doing so. If you do decide to include one, make sure to check whether you need permission from the creator of the image.

Include a note directly beneath the image acknowledging where it comes from, beginning with the word “ Note .” (italicized and followed by a period). Include a citation and copyright attribution . Don’t title, number, or label the image as a figure , since it doesn’t appear in your main text.

Definitional terms often fall into the category of common knowledge , meaning that they don’t necessarily have to be cited. This guidance can apply to your thesis or dissertation glossary as well.

However, if you’d prefer to cite your sources , you can follow guidance for citing dictionary entries in MLA or APA style for your glossary.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, an index is a list of the contents of your work organized by page number.

The title page of your thesis or dissertation goes first, before all other content or lists that you may choose to include.

The title page of your thesis or dissertation should include your name, department, institution, degree program, and submission date.

Glossaries are not mandatory, but if you use a lot of technical or field-specific terms, it may improve readability to add one to your thesis or dissertation. Your educational institution may also require them, so be sure to check their specific guidelines.

A glossary or “glossary of terms” is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. Your glossary only needs to include terms that your reader may not be familiar with, and is intended to enhance their understanding of your work.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, dictionaries are more general collections of words.

An abbreviation is a shortened version of an existing word, such as Dr. for Doctor. In contrast, an acronym uses the first letter of each word to create a wholly new word, such as UNESCO (an acronym for the United Nations Educational, Scientific and Cultural Organization).

As a rule of thumb, write the explanation in full the first time you use an acronym or abbreviation. You can then proceed with the shortened version. However, if the abbreviation is very common (like PC, USA, or DNA), then you can use the abbreviated version from the get-go.

Be sure to add each abbreviation in your list of abbreviations !

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

A list of abbreviations is a list of all the abbreviations that you used in your thesis or dissertation. It should appear at the beginning of your document, with items in alphabetical order, just after your table of contents .

Your list of tables and figures should go directly after your table of contents in your thesis or dissertation.

Lists of figures and tables are often not required, and aren’t particularly common. They specifically aren’t required for APA-Style, though you should be careful to follow their other guidelines for figures and tables .

If you have many figures and tables in your thesis or dissertation, include one may help you stay organized. Your educational institution may require them, so be sure to check their guidelines.

A list of figures and tables compiles all of the figures and tables that you used in your thesis or dissertation and displays them with the page number where they can be found.

The table of contents in a thesis or dissertation always goes between your abstract and your introduction .

You may acknowledge God in your dissertation acknowledgements , but be sure to follow academic convention by also thanking the members of academia, as well as family, colleagues, and friends who helped you.

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .  

In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.

The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

In the discussion , you explore the meaning and relevance of your research results , explaining how they fit with existing research and theory. Discuss:

  • Your  interpretations : what do the results tell us?
  • The  implications : why do the results matter?
  • The  limitation s : what can’t the results tell us?

The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.

In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.

Results are usually written in the past tense , because they are describing the outcome of completed actions.

The results chapter of a thesis or dissertation presents your research results concisely and objectively.

In quantitative research , for each question or hypothesis , state:

  • The type of analysis used
  • Relevant results in the form of descriptive and inferential statistics
  • Whether or not the alternative hypothesis was supported

In qualitative research , for each question or theme, describe:

  • Recurring patterns
  • Significant or representative individual responses
  • Relevant quotations from the data

Don’t interpret or speculate in the results chapter.

An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

In a thesis or dissertation, the acknowledgements should usually be no longer than one page. There is no minimum length.

The acknowledgements are generally included at the very beginning of your thesis , directly after the title page and before the abstract .

Yes, it’s important to thank your supervisor(s) in the acknowledgements section of your thesis or dissertation .

Even if you feel your supervisor did not contribute greatly to the final product, you must acknowledge them, if only for a very brief thank you. If you do not include your supervisor, it may be seen as a snub.

In the acknowledgements of your thesis or dissertation, you should first thank those who helped you academically or professionally, such as your supervisor, funders, and other academics.

Then you can include personal thanks to friends, family members, or anyone else who supported you during the process.
