Two basketball players average the same number of points per game. What information would be most helpful in determining which player’s game performances show the least variability?

Variability describes how spread out a player’s game-by-game scores are. Knowing each player’s highest and lowest game scores lets you compare their ranges: subtract the lowest score from the highest, and the smaller range indicates less variability. The number of games or total points does not show how widely scores varied.
