Just as histograms and dotplots can tell us about the distribution of a quantitative variable, so can a boxplot.

For each boxplot below, choose the description that matches the shape of the data's distribution.

(Note that boxplots can be oriented vertically, as we saw previously, or horizontally, as we see below.)

(a)

A boxplot numbered in increments of 50 from 0 to 350. The low point of the plot is at 50 and the high point is at approximately 290. The low end of the box is at approximately 140, the high end is at approximately 210, and the middle line is at approxima

This distribution is

(b)

A boxplot numbered in increments of 5 from 0 to 25. The low end of the plot is at 0 and the high end is at approximately 8. The low edge of the box is at approximately 1, while the high edge is at approximately 4 and the center line is at approximately 2

This distribution is

(c)

A box plot labeled in increments of 5 from 35 to 60. The low point of the box plot is at 55 and the high point is at approximately 61. The low end of the box is at approximately 56, the high end is at approximately 60, and the middle line is at approxima
