Question

Quizplus · Accepted Answer

Consistency or inconsistency of test scores is related to the concept of reliability. Validity refers to the accuracy of a measure in assessing what it intends to measure, appropriateness considers whether the measure is suitable for the purpose or population being measured, and stability refers to the consistency of scores over time. While all of these concepts are related to the quality of test scores, only reliability specifically deals with the consistency or inconsistency of scores.
