Question

what is mean absolute deviation (MAD) and how do I find it? ​

Answer 1

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