    2.33.

    Step-by-step 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 ...
