The dot plot and box plot show different displays of the ages of runners on a track team.
A dot plot titled Age of Runners goes from 7 to 12. There are 2 dots above 7, 1 above 8, 3 above 9, 2 above 10, 3 above 11, and 2 above 12.

A box-and-whisker plot. The number line goes from 7 to 12 in increments of 0.5. The whiskers range from 7 to 12, and the box ranges from 8.5 to 11. A line divides the box at 10.
Which statements best describe the dot plot or box plot? Check all that apply.
Add the number of dots above each age in the dot plot to find the number of players on the team: 2 + 1 + 3 + 2 + 3 + 2 = 13.
Subtract the maximum and minimum values of the box plot to find the number of players on the team: 12 – 7.
The median appears clearly on the dot plot at the center of the number line: 9.5.
The median appears clearly on the box plot at the line within the box: 10.
The dot plot is the only display that can be used to show the variability of the data.
The box plot is the only display that can be used to show the variability of the data.
