Question

Find: 1. three quartiles, 2. interquartile range (IQR).
2,3, 7, 13, 14, 15, 18, 20, 22, 24, 25

Answer 1

Explanation:

2, 3, 7, 13, 14, 15, 18, 20, 22, 24, 25

`Q_0(minimum)=2` = 2

`Q_1=7`

`Q_2(median)=15`

`Q_3=22`

`Q_4(maximum)=25`

`IQR=Q_3-Q_1`

`IQR=22-7`

`IQR=15`

Hope this helps!
