Document Summary

There are two important criteria of how well measurements and certain research designs fulfill their function: validity : shows how well a measure or design does what it purports to do. Content validity: the adequate sampling of the relevant material or content that a test purports to measure. Convergent and discriminant validity: the grounds established for construct based on the convergent of related tests or behaviour (convergent validity) and thee distinctiveness of unrelated tests or behaviour (discriminant validity) Criterion validity: the degree to which a test or questionnaire is correlated with outcome criteria in the present (concurrent validity) or the future (predictive validity) External validity: the generalizability of an inferred causal relationship over different people, settings, manipulations (or treatments) and research outcomes. Face validity: the degree to which a test or other instruments look as if it is measuring something relevant.
