Question

Quizplus · Accepted Answer

The maximum level of validity possible is equal to the square root of the reliability coefficient. This is because validity is the extent to which a test measures what it is supposed to measure, and reliability is the consistency or stability of test results. The square root of the reliability coefficient gives an indication of how much of the variation in the test scores is due to the true score, which is the part of the score that reflects the construct being measured. Therefore, the square root of the reliability coefficient is the maximum level of validity possible, as it represents the highest amount of variance due to the construct that can be measured by the test.
