Find the mean deviation about the mean for the following data:`6, 7, 10 , 12 , 13 , 4, 8, 12`

Explanation

To find the mean deviation about the mean for the given data set \(6, 7, 10, 12, 13, 4, 8, 12\), we will follow these steps:

### Step 1: Calculate the Mean
First, we need to find the mean (\( \bar{x} \)) of the data.

\[ \bar{x} = \frac{\sum x_i}{n} \]
