9 7 6 8 7 5

 

To find the mean absolute deviation of the data, start by finding the mean of the data set.

[ 9 + 7 + 6 + 8 + 7 + 5 ]  /  6  =    42 / 6  = 7

 

Find the absolute value of the difference between each data value and the mean: |data value – mean|.

l9 -7 l  = 2       l 6 - 7 l = 1     l 7 - 7 l = 0

l 7 - 7l = 0       l 8 - 7 l = 1     l 5  - 7 l = 2

 

Find the sum of the absolute values of the differences.

2 + 0 + 1 + 1 + 0 + 2  =   6

 

 

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

 

6 /6  =   

 

1  =   mean absolute deviation
