Statistical regression is the internal validity problem associated with extreme scores moving toward the mean. This occurs because extreme scores are more likely to be the result of measurement error or chance, while scores closer to the mean are more likely to be representative of the participant's true ability or behavior. Therefore, extreme scores tend to regress toward the mean on subsequent measures.
