In psychology research, validity refers to the extent to which a test or measurement tool accurately measures what it's intended to measure. It ensures that the research findings are genuine and not due to extraneous factors. Validity can be categorized into different types, including construct validity (measuring the intended abstract trait), internal validity (ensuring causal conclusions), and external validity (generalizability of results to broader contexts).| Simply Psychology
Face validity refers to the degree to which a test appears to measure what it is intended to measure. This is often determined from the perspective of the test-taker or an expert.| Simply Psychology
