validity and reliability in quantitative research

Types of reliability and how to measure them. Reliability may be referred to as consistency or stability in some circumstances. If we repeat our measure under very similar conditions, we should get a similar result if our data are reliable. Steps are taken to make sure the work’s findings are the result of experiences and ideas of the informants, and that evaluation findings are arrived at by considering solid evidence. Researchers generally determine validity by asking a series of questions, and will often look for the answers in the research of others. Reliability and Validity Broadly, reliability refers to how repeatable the score or observations are.

The processes within the study are reported in detail, so that a future researcher can repeat the work Is it important to consider the findings of the study within the broader context of other people and settings, and whether similar projects and methods conducted in different environments would be of value. Reliability in qualitative research: Credible The same test conducted by different people.ĭifferent versions of a test which are designed to be equivalent. Reliability and Validity in Quantitative Research Reliability and validity are tools of an essentially positivist epistemology. Reliability in quantitative research: Test-retest the measurement could apply to others/the same result would happen each time The Validity and Reliability of the scales used in research are essential factors that enable the research to yield beneficial results.the extent to which a research instrument consistently has the same results if it is used in the same situation on repeated occasions.
