    MAD = 0

    Step-by-step explanation:

    When I calculated this by hand I got 0. To find the MAD:

    1. You first need to find the mean of the numbers.

    4 + 5 + 8 + 8 + 10 = 35

    35/5 = 7

    the mean value = 7

    2. Then you must find the absolute value of the difference between each data value and the mean: |data value - mean|

    (4 - 7) = - 3

    (5 - 7) = - 2

    (8 - 7) = 1

    (8 - 7) = 1

    (10 - 7) = 3

    3. Add the difference values up

    (-3) + (-2) + 1 + 1 + 3 = 0

    4. Divide the sum of the absolute values of the differences by the number of data values.

    0/5 = 0
