Mrs. little creates a boxplot for the test scores on her latest math test. she finds that the interquartile range is 20 points. what does this mean?

The middle 50% of the scores were 20 points apart.

Step-by-step explanation:

It describes the middle 50% of the value when the data points are ordered from least to highest.

This means that the middle 50% of the scores were 20 points apart.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
