The heights of six basketball players in inches are 75, 78, 77, 79, 83, and 85 What is the mean absolute deviation of the heights?

Mean absolute deviation of the heights is 3.

Explanation:

Given the heights: 75, 78, 77, 79, 83, 85

Average value, X =

                        = 79.5

Mean absolute deviation = (/ - X/ + / - X/ + / - X/ + / - X/ + / - X/ + / - X/)

Mean absolute deviation = (/75 - 79.5/ + /78 - 79.5/ + /77 - 79.5/ + /79 - 79.5/ + /83 - 79.5/ + /85 - 79.5/)

                              =  (4.5 + 1.5 + 2.5 + 0.5 + 3.5 + 5.5)

                              =  (18)

                              = 3

The mean absolute deviation of the heights is 3.
