Question

What is the IQR (Inter Quartile Range
0, 21, 45, 3, 1, 5, 25

Answer 1

Interquartile range = 24

Explanation:

First we need to put the sequence in order from lowest to highest.

0, 1, 3, 5, 21, 25, 45

5 is the median and then from 5 to 0 we need to find the lowest interquartile in between it which is 1.

Highest interquartile from 5 to 45 finding the middle will be 25.

Interquartile range = highest interquartile - lowest quartile

25-1 = 24
