Answer with explanation:

  • The mean absolute deviation (MAD) of a data set is the mean of the absolute distances from the mean.

Steps to find MAD:

Step 1. Calculate mean(
\overline{x}) of the data using formula:
\overline{x}=(\sum x)/(n) , where x denotes data points and n is the number of data points.

Step 2. Calculate distance of each data point from mean :

Distance =
|x-\overline{x}|

Step 3. Divide distance of each data point from mean by n:

MAD =
\frac{\sum |x-\overline{x}|}{n} , which is the final computation to find MAD.
