Median: 16

Lower quartile: 11

Upper quartile: 22

interquartile range: 22 - 11 = 11

Answer 2

The IQR is the interquartile range
First find the median which is 16
Then find the median in the first set of numbers so it would be 11
Next find the median for the second half which is 22
then subtract the two so 22-11
Your IQR is 11
