The first quartile of a data set is 52, and the third quartile is 72. Which of these values in the data set is an outlier?

Given:

iq1 - 52

iq3 - 72

iq3 - iq1 = iqr

72 - 52 = 20

inner fence = minor outlier

20 * 1.5 = 30

72 + 30 = 102

52 - 30 = 22

outer fence - major outliers

20 x 3 = 60

72 + 60 = 132

50 - 60 = - 10
