Statistical regression is the tendency for extreme scores on a test to regress toward the mean on a subsequent test. This phenomenon explains why the person who originally scored a 165 (an extremely high score) scored lower on the second test, while the person who originally scored a 112 (an extremely low score) scored higher on the second test. Testing, instrumentation, and maturation do not account for the observed differences in scores.
