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}=(\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.
