Question

Quizplus · Accepted Answer

Reliability refers to the consistency or stability of a measure over time or across different conditions. Therefore, choice C "consistency" is the best choice as it accurately reflects the meaning of reliability. Choices A, B, and D are incorrect. A) "Consistently good" implies that the measure is always accurate, which is not necessarily true with reliability. B) "Consistently bad" implies that the measure consistently produces inaccurate results, which is also not the definition of reliability. D) Validity refers to whether a measure is measuring what it is intended to measure, which is related to but distinct from reliability.
