Answer

Answer:

B. median

Explanation:

Step1: Recall box - plot features

A box - plot shows the five - number summary: minimum, first quartile ($Q_1$), median, third quartile ($Q_3$), and maximum.

Step2: Analyze measure of center

The mean is not shown on a box - plot. The range and IQR are measures of spread (range = maximum - minimum, IQR=$Q_3 - Q_1$). The median is the middle value of the data set and is represented by the line inside the box of the box - plot. So the measure of center that can be determined and compared in box - plots is the median.
