Question

Quizplus · Accepted Answer

Inconsistent scores do not provide a good measure of stable traits or attributes as they may be affected by factors outside of the test-taker's abilities. Consistency in test scores is important to ensure reliable measurement of the construct being assessed. Option A is partially correct as consistency does indicate that the test is measuring what it is designed to measure, but it is not the only reason why consistency is important. Option B is incorrect as giving inconsistent tests many times would not improve the quality of the measurement. Option D is incorrect as ability can change over time.
