Generation

Regression to the mean is the statistical phenomenon where extreme performances tend to be followed by more average performances. This occurs because any performance consists of true ability plus random variation, so unusually high or low results likely included favorable or unfavorable randomness that won't repeat. The key relationship is: **Expected next performance = overall mean + r(current performance - overall mean)**, where r is the correlation between performances (0 < r < 1). The weaker the correlation (smaller r), the stronger the regression to the mean.
