In psychometrics, criterion validity, or criterion-related validity, is the extent to which an operationalization of a construct, such as a test, relates to, or predicts, a theoretical representation of the construct—the criterion. Criterion validity is often divided into concurrent and predictive validity based on the timing of measurement for the "predictor" and outcome. Concurrent validity refers to a comparison between the measure in question and an outcome assessed at the same … Webbadj. 1 of or based on theory. 2 lacking practical application or actual existence; hypothetical. 3 using or dealing in theory; impractical. ♦ theoretically adv.
