Question

Which data values are outliers?
71, 96, 110, 112, 114, 114, 121, 127, 135, 175, 180

Answer 1

Answer: 71, 175, 180

Explanation:

Find the interquartile range. 127- 112 = 23 Multiply by 1.5 = 34.5

Add to the mean 114 + 34.5 = 148.5

Subtract from the mean 114 - 34.5 = 79.5

Any number greater than 148.5 or less than 79.5 is considered an outlier
