What is a(n) __________ test measures what it is supposed to measure.?

A validity test measures the degree to which the test accurately assesses the specific construct or skill it is intended to measure. In other words, it determines whether the test is measuring what it claims to measure. There are different types of validity tests, including content validity, criterion-related validity, and construct validity. Content validity ensures that the test covers all aspects of the construct it is meant to measure, while criterion-related validity refers to how well the test predicts a particular criterion outcome. Construct validity assesses how well the test measures an underlying theoretical construct. Ultimately, validity is crucial in ensuring the reliability and usefulness of a test in making accurate assessments and decisions.
