D) discriminant evidence of validity

Question

Convergent evidence of validity refers to the degree to which a test correlates with other tests that measure the same construct. Therefore, when scores on a test correlate strongly with scores on other tests that measure the same construct, we say the test has convergent evidence of validity. Option A "evidence of validity based on content" is not applicable here as it refers to the extent to which a test covers the domain of interest. Option B "evidence of validity based on relations with external criteria" is also not the best choice as it refers to the ability of the test to predict future performance on a related criterion. Option D "discriminant evidence of validity" refers to the degree to which a test does not correlate with other tests that measure different constructs.
