Question

Help me to find the interquartile range

Answer 1

4

Explanation:

The Interquartile range is always the width of the box. So, here, you can count the number of spaces on the number line between the lower end of the box and the upper end of the box. Alternatively, subtract the value of the lower end of the box (11) from the upper end of the box (8).

11-8 = 4

Answer 2

The interquartile range is 3.

Explanation:

Median: 10

Highest value: 13

Lowest Value: 4

(Q1) lower quartile: 8

(Q2) upper quartile: 11

(IQR) interquartile range: 11 - 8 = 3
