Procedures for Assessing the Validities of Tests Using the "Known-Groups" Method

Abstract

If a test is "valid," one criterion could be that test scores must discriminate across groups that are theo retically known to differ. A procedure is outlined to assess the discrimination across groups that uses only information from means. The method can be applied to many published tests, it provides information that relates to the construct validity of the test, and it pre sents a way to identify how a new sample can be re lated to previous studies.
