Question

Quizplus · Accepted Answer

The length of the box in a box plot represents the interquartile range (IQR), which is the range between the first quartile (Q1) and third quartile (Q3). The median is represented by a line inside the box. The mean is not typically shown in a box plot. The range is represented by the whiskers of the plot, which extend to the minimum and maximum data points, but are limited to a certain length (e.g. 1.5 times the IQR).
