The double box-and-whisker plot shows the goals scored per game by two hockey teams during a 20-game season. a. Compare the populations using measures of center and variation.

Team A: median = 3, IQR = 2
Team B: median = 7, IQR = 2
The variation in the goals scored is the same, but Team B usually scores about 4 more goals per game.

Team A: median = 3, IQR = 2
Team B: median = 7, IQR = 2
The variation in the goals scored differs by 4, but the number of goals scored per game is the same.

Team A: median = 6, IQR = 2
Team B: median = 10, IQR = 2
The variation in the goals scored is the same, but Team B usually scores about 4 more goals per game.

Team A: median = 6, IQR = 2
Team B: median = 10, IQR = 2
The variation in the goals scored differs by 4, but the number of goals scored per game is the same.
b. Express the difference in the measures of center as a multiple of the measure of variation.

The difference in the medians is times the IQR.
