What is the mean absolute deviation of this data set? 26, 31, 32, and 39

3.5

Step-by-step explanation:

26, 31, 32, and 39

First we need to find the mean

(26 + 31 + 32 + 39) / 4

128/4 = 32

The mean absolute deviation is sum of the positive difference between the number and the mean divided by the number of terms

((32-26) + (32-31) + (32-32) + (39-32)) / 4

14/4

3.5
