Question

Using the following data, calculate the mean absolute deviation:

7 2 8 5 9 9 5 6 8 1


What is the mean absolute deviation for these data?

Answer 1

kphung76127 is right. It is 2.2

Explanation:

I got it right on a test.

Answer 2

First calculate the mean
7+2+8+5+9+9+5+6+8+1=60
60/10=6 = mean
To calculate MAD, find the mean of the differences between each value and the mean.
1+4+2+1+3+3+1+0+2+5=22
22/10=2.2
Final answer: 2.2
