Quizplus · Accepted Answer

Regression toward the mean is the tendency for extreme scores or behaviors to return to their average. The fact that the student scored a 95% on the first exam, which is above their average, means it is likely that they will score lower on the next exam, closer to their average of 83%. This is not an example of the Hawthorne effect, maturation, or attrition.
