Primes

• Simpson–Yule Effect
  • In sports, one player can have a higher per-season average than another across every season yet a lower career average, if they faced different mixes of easy and hard years.

    This sourcePresents the Derek Jeter vs. David Justice batting-average case (1995–1996): Justice has the higher average in each individual season, yet Jeter has the higher combined average — the canonical sports Simpson's-paradox instance driven by unequal at-bat counts across years.

• Simpson's Paradox
  • Public policy and program evaluation: a programme raises scores in every demographic subgroup while aggregate scores fall, because it attracts harder-to-serve participants — and without sub-group analysis the policy looks harmful. Sports analytics: a player out-hits a rival in every season but trails on career average, because their seasons cluster in pitcher-friendly, low-at-bat eras.

    This sourcePresents the batting-average instance of Simpson's paradox (the Justice/Jeter case) where one player leads in each individual season yet trails on the combined average.
