Someone's quoting 'the average' to make a point. Pick which middle, mean, median or mode, tells the truth, and call out the spin.

How to play
Each round shows a small dataset and a claim that quotes one measure of center. Decide which of mean, median or mode is the honest summary for that data, then judge whether the report's claim is misleading. Skewed data and outliers make the mean a liar more often than you'd expect. Both answers together earn the round.
A game runs six rounds with a running score.
Skewed datasets reward the median; the mean gets dragged by outliers.
A fast finish earns a small speed bonus.
