Mean Absolute Deviation formula

MAD Mean Absolute Deviation Formula

For example, when date set is {5,20,40,80,100}, then Mean Absolute Deviation(MAD) = 32.8.

Total Inputs(N) =(5,20,40,80,100)

Total Inputs(N)=5

Mean(xm)= (x1+x2+x3...xN)/N

Mean(xm)= 245/5

Means(xm)= 49

-------------------------------------------

MAD=1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)

=1/5(|5-49|+|20-49|+|40-49|+|80-49|+|100-49|)

=32.8
