Answer:

2.33.

Explanation:

First we find the mean by adding the values and dividing by 11 (the number of values).

mean = 62 / 11

= 5.636

Now, we list the absolute differences between each value and the mean:

9 - 5.636 = 3.364 the others are:

3.636, 3.636, 0.636, 2.636, 3.364, 0.364, 4.364, 1.636, 1.364, 0.636

Now the MAD is the sum of these values / 11.

MAD = 25.636/11

= 2.33..
