Data:
15 16 14 15 19 17
n=6 points
sum is 96
mean is 96/6 = 16
Now we look at the absolute deviations, each of which is the absolute value of a score minus the mean, basically the distance of the score to the mean .
Scores   15 16 14 15 19 17
AbsDev    1  0  2  1    3  1
The sum of the absolute deviations is 8 and there are six of them so the 
Mean Absolute Deviation = 8/6 = 4/3
Answer: 2.    8/6
