Although validity in qualitative research has been widely reflected upon in the methodological literature (and is still often subject of debate), the link with evaluation research is underexplored. how validity and reliability are achieved in quantitative research? Answer. Keywords: qualitative research, quality, validity, reliability, generalizability, accounting 1 Azham Md. With reference to definitions of validity and reliability, and drawing extensively on conceptualisations of qualitative research, this essay examines the correlation between the reliability of effort to find answers to questions about the social
They indicate how well a method , technique or test measures something.
Unlike quantitative research where validity depends on the soundness of the instrument, validity in qualitative research depends on the ability and effort of the researcher in ensuring credibility, transferability, dependability, and conformability. Because, although the term ‘reliability’ is usually applied as a concept for testing or evaluating quantitative research, the idea is also used in all kinds of research. Reliability refers to the extent to which the same answers can be obtained using the same instruments more than one time. (KW, 02-2020) Qualitative Validity. Validity and reliability as quality indicators have an uneasy standing in qualitative research and are subject to numerous debates.
In this article, I will explore aspects of validity of qualitative research with the explicit objective of connecting them with aspects of evaluation. the validity and reliability of quantitative research cannot be applied to qualitative research, there are ongoing debates about whether terms such as validity, reliability and generalisability are appropriate to evalu-ate qualitative research.2–4 In the broadest context these terms are applicable, with validity referring to the integ- In short, it is the repeatability of your measurement. Reliability. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure. The table below compares the factors influencing validity within qualitative and quantitative research contexts (Cohen, et al., 2011 and Winter, 2000): Qualitative research. Issues of research reliability and validity need to be addressed in methodology chapter in a concise manner.. Ignore the ones in the slides: use this materials as you like, with attribution. Since qualitative researchers do not use instruments with established metrics about validity and reliability, it is pertinent to address how qualitative researchers establish that the research study’s findings are credible, transferable, confirmable, and dependable. This chapter discusses issues of the reliability and validity of our measuring instruments, and the reliability as well as the internal and external validity of our research as a whole.
