C) standard error of measurement
D) correlation coefficient

Question

Quizplus · Accepted Answer

The statistic that reflects the amount of inconsistency or error expected in an individual's test score is the standard error of measurement. This takes into account factors such as the reliability of the test and the individual's own variability in performance. The reliability coefficient (A) measures the consistency of scores on a test and is often used to estimate the standard error of measurement. The standard deviation (B) measures the variability of a set of scores, but does not specifically account for error or inconsistency in individual scores. The correlation coefficient (D) measures the strength and direction of a relationship between two variables, but is not directly related to the consistency or error in individual test scores.
