Find mean deviation about the mean for the following data :`x_i` 2 5 6 8 10 12`f_i` 2 8 10 7 8 5

Explanation

To find the mean deviation about the mean for the given data, we will follow these steps:

### Step 1: Organize the Data
We have the following data given:
- \( x_i \): 2, 5, 6, 8, 10, 12
- \( f_i \): 2, 8, 10, 7, 8, 5

We will organize this data into a table for easier calculations.
