Question

Quizplus · Accepted Answer

For a psychological test to be useful, it must be reliable, meaning it consistently yields the same results, and valid, meaning it measures what it is supposed to measure. Therefore, the best choice is C, as both factors are crucial for a psychological test to be effective. Accuracy (A) and representativeness (D) are also important, but they do not ensure that the test is measuring what it is supposed to measure. Convergent validity (B) is important, but it only addresses the relationships between the test and other measures, not the test's ability to measure what it is supposed to measure.
