Question

Quizplus · Accepted Answer

Dr. Sardonicus can determine test-retest reliability by correlating the two sets of scores. This measures the consistency of the test over time, as it is administered to the same group of test takers in the same setting. It does not measure validity, internal reliability, or convergent validity.
