Quizplus · Accepted Answer

A test is considered to be reliable if its reliability coefficient is greater than .90. This means that the test is consistent and yields the same or similar results each time it is administered. A reliability coefficient below .90 indicates that there is a significant amount of measurement error and the test results may not be trustworthy or accurate. Therefore, choice D is the best choice as it indicates a high level of reliability.
