Question

Delilah Boucher · Accepted Answer

Final Answer : D, Explanation :  The best way to measure the reliability of a test is through determining whether the people who score high on the test one time will also score high the next time they take the test. This is known as test-retest reliability and it indicates the consistency of scores over time. Options A, B, and C are not necessarily measures of reliability, although they are important considerations in test development and evaluation.
