Question

Discriminant validity refers to the ability of a test to distinguish between constructs that are supposed to be different. Extraversion and introversion are two separate constructs, and a test that is able to accurately differentiate between them has good discriminant validity. A test with test-retest reliability measures consistency of scores over time, internal consistency measures consistency across items within a test, convergent validity measures the degree to which scores on one test correspond with scores on another test thought to measure the same construct, and divergent validity measures the degree to which scores on one test do not correspond with scores on another test thought to measure a different construct. While these are all important aspects of test validity and reliability, none specifically address the ability to differentiate between extraverts and introverts.
