Question

Quizplus · Accepted Answer

The term used to describe the consistency and stability of test scores over time is reliability. The fact that most people got very similar scores each time they took the test indicates that the test is reliable. Option A (accurate) and B (valid) are not necessarily true just because the scores were consistent, as accuracy refers to whether the test is measuring what it is supposed to measure and validity concerns the degree to which a test measures what it claims to measure. Option C (generalized) does not accurately describe the test in question.
