Question

The data set is 49, 47, 17, 16, and 10.5. What’s the mean absolute deviation?

Answer 1

16.08

Explanation:

Mean: 10.5 + 16 + 17 + 47 + 49 = 139.5/5 = 27.9

27.9 - 10.5 = 17.4

27.9 - 16 = 11.9

27.9 - 17 = 10.9

27.9 - 47 = 19.1

27.9 - 49 = 21.1

10.9 + 11.9 + 17.4 + 19.1 + 21.1 = 80.4/5 = 16.08

Mean Absolute Deviation: 16.08
