Question

What is the interquartile range of 6.3, 6.4, 6.5, 6.6, 6.8, 6.8, 7.5

Answer 1

Hello!

First you have to find the median

6.3, 6.4, 6.5, 6.6, 6.8, 6.8, 7.5

The median is 6.6

Next you find quartile 1

quartile 1 is the median of the numbers less than 6.6

6.3, 6.4, 6.5

The median is 6.4

Next you find quartile 3

quartile 3 is the median of the numbers higher than the median

6.8, 6.8, 7.5

The median is 6.8

Then you find the range of quartile 3 and quartile 1

You subtract quartile 1 from quartile 3

6.8 - 6.4 =0.4

The interquartile range is 0.4

Hope this helps!
