Question

Zahra was given two data sets, one without an outlier and one with an outlier. data without an outlier: 15, 19, 22, 26, 29data with an outlier: 15, 19, 22, 26, 29, 81how is the median affected by the outlier?

Answer 1

The outlier slightly affected the median.

Answer 2

data without an outlier...15,19,22,26,29...and the median is 22

data with an outlier...15,19,22,26,29,81...and the median is (22 + 26) / 2 =
48/2 = 24

the median with the outlier is 2 points higher then the median without the outlier....so the outlier did affect the median...but not by much
