Example
NCAA Soccer Players
Soccer players who play more games have more opportunities to score goals, so it isn't quite fair to simply look at the number of goals scored in a season. Instead, consider Figure, which shows the number of goals per game (the number of goals a player scores divided by the number of games that she or he played) for women and men first-year players.
Figure
Distribution of goals per game scored during one season for (a) women and (b) men.
QUESTION
Do these men and women soccer players have different variability in the goals scored per game? If so, which group has the greater variability?
