Question

Can someone help me with comparing sets?

Answer 1

The box plots show male and female grades in a U.S. history class:

two bar graphs shown. The top one is labeled Male. Minimum at 70, Q1 at 82, median at 88, Q3 at 95. The bottom bar graph is labeled Female. Minimum at 75, Q1 at 78, Q3 at 90, maximum at 92.

Which of the following best describes the information about the interquartile ranges?

The female interquartile range cannot be known because only three quartiles are showing.
The male interquartile range cannot be known because the fourth quartile is missing.
The male interquartile range is larger due to the size of the first quartile.
The two interquartile ranges are about the same size.
