Students reported volunteering at the animal shelter during the last 6 months for 25, 36, 31, and 32 hours. What is the mean absolute deviation for the number of hours students volunteered? Round to the nearest tenth.

0

3

4

6

The correct answer for the question that is being presented above is this one: "3"

(1) First get the mean: 25 + 36 + 31 + 32 / 4 = 31

(2) Find the distance of each value to the mean: 31-25 = 6; 36-31=5; 31-31=0; 32-31=1

(3) Get the mean of the distance: 6 + 5 + 0 + 1 / 4 = 3

So the mean deviation is 3.
