Question

Based on the box-and-whisker plot shown below, match each term with the correct value.

Answer 1

Median = 18

This is the middle line in the box.

Range = 6

This is the difference between the highest and lowest values, 21 - 15.

25th percentile = 17

This is the Q1 value, which is the left side of the box.

75th percentile = 20

This is the Q3 value, which is the right side of the box.

Interquartile range = 3

This is Q3-Q1, which is 20 - 17. This is another way to measure spread.
