Reliability and validity are closely related, but they mean different things. A measurement can be reliable without being valid. However, if a measurement is valid, it is usually also reliable.
Reliability can be estimated by comparing different versions of the same measurement. Validity is harder to assess, but it can be estimated by comparing the results to other relevant data or theory. Methods of estimating reliability and validity are usually split up into different types.
The reliability and validity of your results depends on creating a strong research design, choosing appropriate methods and samples, and conducting the research carefully and consistently.
It’s appropriate to discuss reliability and validity in various sections of your thesis or dissertationor research paper. Showing that you have taken them into account in planning your research and interpreting the results makes your work more credible and trustworthy.
In a nutshell, reliability relates to the consistency of measures, and validity addresses whether the measurements are quantifying the correct attribute. In this post, learn about reliability vs. validity, their relationship, and the various ways to assess them.
There are two distinct criteria by which researchers evaluate their measures: reliability and validity. Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability). Validity is the extent to which the scores actually represent the variable they are ...

Aug 15, 2024 · In this article, we discuss measurement validity and reliability, including types, examples and tips, and review the relationship between measurement validity and reliability in research.
Sep 27, 2024 · Reliability is a necessary condition of validity: a measure that is valid must also be reliable. An instrument that is properly measuring a construct of interest should yield consistent results. However, a measure can be reliable but not valid.
Jul 26, 2023 · A measurement instrument is considered reliable if it consistently produces the same results when it is used repeatedly to measure the same thing. In other words, it is a reliable instrument that produces consistent results, regardless of who administers it, when it is administered, and under what conditions it is administered.
