Find the mean deviation from the mean for the data: 6,7,10,12,13,4,8,12.

Explanation

To find the mean deviation from 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 of the data set.

\[ \text{Mean} = \frac{\text{Sum of all data points}}{\text{Number of data points}} \]
