Abstract

If a test is "valid," one criterion could be that test scores must discriminate across groups that are theoretically 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 presents a way to identify how a new sample can be related to previous studies.
