Explanation:

The mean is calculated in the usual way: the sum divided by the number of numbers.

mean = (5 +9 +5 +5 +7 +11)/6 = 7

The deviations are the differences from the mean:

deviation = {5, 9, 5, 5, 7, 11} -7 = {-2, 2, -2, -2, 0, 4}

and the absolute deviation is the absolute value of these numbers:

absolute deviation = {2, 2, 2, 2, 0, 4}

The mean absolute deviation (MAD) is the average of these values:

(2 +2 +2 +2 +0 +4)/6 = 2

The mean absolute deviation is 2.

It is generally convenient to let technology do the computation. A spreadsheet or graphing calculator can do this easily.
