Say you have a data set {4,6,8,9,10}

1. Find the mean = (4+6+8+9+10)/5=7.4

2. Sum the deviations from the mean (absolute values, no negatives)

|(4-7.4)|+|(6-7.4)|+|(8-7.4)|+|(9-7.4)|+|(10-7.4)| = 9.6

3. Divide the sum by the number of data (n=5) to get 9.6/5=1.92

4. 1.92 is the mean absolute deviation required.
