Question

Which of the following is not needed when making a box plot?

A - Mean
B - Minimum
C - Median
D - Third Quartile

Answer 1

Answer: A) Mean

You use the median as the center of the boxplot. The first and third quartiles (Q1 and Q3) make up the left and right edges of the box. The min and max are the furthest points on the left and right side of each whisker. The mean is not used at all. With outliers, the mean is skewed. If you have any outliers then its best to use the median instead.

Answer 2

The mean is not needed to make a box plot.
