Regression to the mean is a statistical phenomenon where extreme or unusual observations tend to be followed by more typical or average observations. It suggests that over repeated measurements or observations, extreme values are likely to move closer to the population mean or average. Regression to the mean occurs because extreme values are often influenced by random variation or measurement error, rather than a consistent underlying trend or pattern.

Extreme results don’t last forever. Things tend to average out over time – that’s Regression to the Mean. ⚖️📊 #RegressionToTheMean #Statistics #MentalModels
