In particular, many research mistakes occur due to problems associated with research validity and research reliability. Validity and reliability are important concepts in research. In research, no two concepts are more confused with one another than validity and reliability. For instance, 9 Lecompte and Goets, (1982) in their work ‘Problems of Reliability and Validity in Ethnographic Research’ mention two forms of validity in relation to qualitative research; Internal validity, meaning a sound contest between researcher’s observation and the theoretical ideas they develop and; external validity, as the amount of generalizability of the findings. Reliability; Reliability & Validity; Reliability & Validity. Reliability and validity in qualitative research. When handled meticulously, the reliability and validity parameters help differentiate between good and bad research. We often think of reliability and validity as separate ideas but, in fact, they’re related to each other. A credible researcher minimizes possible errors and bias by maximizing the reliability and validity of data. Validity and reliability of qualitative research represent the key aspects of the quality of research.

This problem with data gathering represents several concepts that to the non-researcher may be quite complex. Introduction. It’s not necessarily the difference between them that is so baffling; it’s more the fact that there is so much more to it. validity and reliability as they relate to behavioural research. This is important if the results of a study are to be meaningful and relevant to the The tricky stuff comes when we examine the different types of validity and reliability. how validity and reliability are achieved in quantitative research? Keywords: Validity and reliability, errors in research, threats in research. Beverly Hills: Sage Publications. The validity of the research findings are influenced by a range of different factors including choice of sample, researcher bias and design of the research tools. Reliability estimates evaluate the stability of measures, internal consistency of measurement instruments, and interrater reliability of instrument scores. Like reliability and validity as used in quantitative research are providing springboard to examine what these two terms mean in the qualitative research paradigm, triangulation as used in quantitative research to test the reliability and validity can also illuminate some ways to test or maximize the validity and reliability of a qualitative study. The main difference between validity and reliability is that validity is the extent to which a test measures, and what it claims to measure whereas reliability refers to the consistency of the test results.. Tests or research of any kind is measured upon validity and reliability. Instrument: A valid instrument is always reliable. Here, I want to show you two ways you can think about their relationship.

The paper has been written for the novice researcher in the social sciences. In research, reliability and validity are often computed with statistical programs. This PsycholoGenie post explores these properties and explains them with the help of examples. & Niwa, S. (1985). Research Reliability Reliability refers to whether or not you get the same answer by using an instrument to measure something more than once. Students associated with the research field have confusion between reliability and validity. Inter-rater reliability is useful because human observers will not necessarily interpret answers the same way; raters may disagree as to how well certain responses or material demonstrate knowledge of the construct or skill being assessed. In simple terms, research reliability is the degree to which research method produces stable and consistent results. In different contexts, research is a clearly defined process where different elements and are studied, analysed and presented to show new approaches that increase knowledge regarding a particular phenomenon. Validity, reliability and generalization are important concepts in business and management research. Inter-rater reliability is a measure of reliability used to assess the degree to which different judges or raters agree in their assessment decisions.
