what is the mad for 3 3 8 2 1

The MAD (Mean Absolute Deviation) is calculated as follows:

 

First find the mean  μ = (3 + 3 + 8 + 2 + 1)/5 = 17/5

 

Now calculate the absolute values of the deviations from the mean, add these up and divide by 5:

 

MAD = (|3 - 17/5| + |3 - 17/5| + |8 - 17/5| + |2 - 17/5| + |1 - 17/5|)/5

 

I'll leave you to crunch the numbers.
