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 is the difference between the maximum and minimum values. The IQR (inter - quartile range) is $Q_3 - Q_1$. The median is the middle value of the data set and is represented by the line inside the box in a box - plot. So, the measure of center that can be determined and compared in box plots is the median.
