Quizplus · Accepted Answer

The score reliability of test B is lower than that of test A, indicating that the scores on test B are less consistent from one administration to the next. Additionally, the standard deviation for test B (8) is smaller than that of test A (10), meaning that the scores on test B are clustered more tightly around the mean. Both of these factors suggest that a student's score on test B would be expected to fluctuate more on repeated administrations than their score on test A. Therefore, the best choice is B.
