Mean Absolute Deviation Worksheet

This worksheet may help you to know about the Mean Absolute Deviation.The median absolute deviation (MAD) is a robust measure of the variability of a univariate sample of quantitative data. MAD - Mean absolute deviation of an element of a data set is the absolute difference between that element and a given point. The formula used to calculate Mean absolute deviation is,

Mean Absolute Deviation Example

Calculate Mean absolute deviation whose inputs are 10, 20,30,40,50
Total Inputs(N) =(10,20,30,40,50)
Total Inputs(N)=5
Mean (xm)= (x1+x2+x3...xN)/N
Mean (xm)= 150/5
Means (xm)= 30
MAD = 1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)
MAD = 1/5(|10-30|+|20-30|+|30-30|+|40-30|+|50-30|)
MAD = 1/5(20+10+0+10+20))
MAD =12

The above worksheet is an walk through to understand the concept of Mean Absolute Deviation. When it comes to online calculation this online Mean Absolute Deviation Calculator is an essential tool to make the calculation easy.
