Detailed explanation-1: -the extent to which a test samples the behavior that is of interest (such as a driving test that samples driving tasks). the behavior (such as future college grades) that a test (such as the SAT) is designed to predict; thus, the measure used in defining whether the test has predictive validity.

Detailed explanation-2: -*Validity-the extent to which a test measures or predicts what it is supposed to.

Detailed explanation-3: -Reliability: The extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting. Validity: The extent to which a test measures or predicts what it is supposed to.

Detailed explanation-4: -Predictive validity refers to the extent to which scores on a measurement are able to accurately predict future performance on some other measure of the construct they represent.
