validity in case study research

Several methods can be employed in qualitative methodology, as indicated by Queirós et al. (2017): (i) observation; (ii) ethnography; (iii) field research; (iv) focus groups; or (v) case studies. The case study is a qualitative method that generally consists of a way to deepen an individual unit.

validity and reliability of the case study evidence which are; (1) multiple sources of evidence; (2) create a case study database; and (3) maintain a chain of evidence. With regards to rigour and thoroughness in case study process, the elements of construct validity, internal validity, external validity and reliability is the strategy used to ...

The case study can be used for two main purposes: explorato ry and. descriptive (Yin, 2017). The exploratory study contributes to clarify a. situation where information is scarce. The level of ...

In assessing validity of qualitative research, the challenge can start from the ontology and epistemology of the issue being studied, ... Most qualitative research studies, if not all, are meant to study a specific issue or phenomenon in a certain population or ethnic group, of a focused locality in a particular context, hence generalizability ...

However, there is no single, coherent set of validity and reliability tests for each research phase in case study research available in the literature. This article presents an argument for the case study method in marketing research, examining various criteria for judging the quality of the method and highlighting various techniques, which can ...

Validity and generalization continue to be challenging aspects in designing and conducting case study evaluations, especially when the number of cases being studied is highly limited (even limited to a single case). To address the challenge, this article highlights current knowledge regarding the use of: (1) rival explanations, triangulation ...

Central to all research is the goal of finding plausible and credible outcome explanations using the concepts of reliability and validity to attain rigor as "without rigor, research is worthless, becomes fiction, and loses its utility" (Morse et al. 2002:14).The validity of theory or findings (assuring that what is measured accurately reflects what is intended) and reliability (assuring ...

These few authors argue that the broad and abstract concepts of reliability and validity can be applied to all research because the goal of finding plausible and credible outcome explanations is central to all research (Hammersley, 1992; Kuzel & Engel, 2001; Yin, 1994). We are concerned, nonetheless, that the focus on evaluation strategies that ...

Focusing on the case study method helps to answer the identified research questions in an explanatory, descriptive way and also helps to construct validity and reliability which works as a medium ...

Abstract. Despite the advantages of the case study method, its reliability and validity remain in doubt. Tests to establish the validity and reliability of qualitative data are important to determine the stability and quality of the data obtained. However, there is no single, coherent set of validity and reliability tests for each research ...

When a test has strong face validity, anyone would agree that the test's questions appear to measure what they are intended to measure. For example, looking at a 4th grade math test consisting of problems in which students have to add and multiply, most people would agree that it has strong face validity (i.e., it looks like a math test).

Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.opt. It's important to consider reliability and validity when you are creating your research design, planning your methods, and writing up your results, especially in quantitative research. Failing to do so can lead to several types of research ...

Validity and reliability tests in case study research: a literature review with "hands-on" applications for each research phase ... Case study research is suited to studying theories in this way because it only takes one case that is inconsistent with a theory to disconfirm it (Easterby-Smith et al., 1991, p. 139). ...

Validity. Validity is defined as the extent to which a concept is accurately measured in a quantitative study. For example, a survey designed to explore depression but which actually measures anxiety would not be considered valid. The second measure of quality in a quantitative study is reliability, or the accuracy of an instrument.In other words, the extent to which a research instrument ...

The validity of a research study refers to how well the results among the study participants represent true findings among similar individuals outside the study. This concept of validity applies to all types of clinical studies, including those about prevalence, associations, interventions, and diagnosis.

External Validity: External validity refers to the extent to which research findings can be generalized to settings, populations, and times beyond the specific conditions of the study. It's crucial for determining whether the conclusions drawn from a study can apply to real-world scenarios, as well as how the results can be interpreted across ...

There are several terms used to describe the approaches to assessing internal validity of primary research studies, including evidence hierarchies and levels of evidence, quality assessment, and risk of bias assessment. The use of these terms may be confusing, and it is not uncommon for some of these terms to be used interchangeably (14, 15 ...

A case study is one of the most commonly used methodologies of social research. This article attempts to look into the various dimensions of a case study research strategy, the different epistemological strands which determine the particular case study type and approach adopted in the field, discusses the factors which can enhance the effectiveness of a case study research, and the debate ...

This paper aims to fill this gap by reviewing the exis ting literature related to. validity and reliability issues in case study resear ch in accounting while drawing on the. systematic analytical ...

Background: Validity is a core topic in educational and psychological assessment. Although there are many available resources describing the concept of validity, sources of validity evidence, and suggestions about how to obtain validity evidence; there is little guidance providing specific instructions for planning and carrying out validation studies.

Recent research shows that one commonly employed tactic — turning off social media comments — can undermine influencers' key assets: their persuasiveness, likability, and perceived sincerity.

Academic and research units. If you're looking to narrow down your research interests and identify a field of study that appeals to you, the main university list of colleges, schools, departments and other academic units can help you find a program.. The Office of the Vice President for Research provides a list of research units, and also highlights the ongoing work at UT's research centers.

However, the increased importance given to qualitative information in the evidence-based paradigm in health care and social policy requires a more precise conceptualization of validity criteria that goes beyond just academic reflection. After all, one can argue that policy verdicts that are based on qualitative information must be legitimized by valid research, just as quantitative effect ...
