Do they produce correct results? Are they applicable for this subject? Both validity and reliability values make it possible to quickly evaluate how well your research approach works in a particular case. Why is it important to know the difference between reliability vs validity? Conducting complex research typically requires some preparation, particularly to evaluate your data collection and analysis methods. A valid study measures what it is supposed to measure and its results can be applied to the population of interest. Validity means the accuracy or truthfulness of research findings.Research is considered reliable if it produces identical outcomes when repeated under similar conditions.

Reliability refers to the consistency of research findings over time or across different studies.Reliability and validity are two important concepts in research design that are used to assess the quality of research results.
