Question 3 • Concepts in Probability and Statistics

A data set has a maximum of 200, a minimum of 115, a median of 145, an upper quartile of 150, and a lower quartile of 120. Which statement is true of the box plot of this data set?

Answer
A
The right whisker will go from 150 to 200.
B
The left whisker will go from 115 to 145.
C
A line dividing the box will be at 135.
D
The box will go from 145 to 150.

Explanation

In a box plot, the box extends from the lower quartile (120) to the upper quartile (150), with a line at the median (145). The right whisker extends from the upper quartile to the maximum, so it goes from 150 to 200. Therefore, the true statement is that the right whisker will go from 150 to 200.
