Calculate mean deviation from the median for the following distribution: `x_i :` 10 15 20 25 30 35 40 45 `f_i :` 7 3 8 5 6 8 4 9

Explanation

To calculate the mean deviation from the median for the given distribution, we will follow these steps:

### Step 1: Create a frequency table
We will list the values of \( x_i \) and their corresponding frequencies \( f_i \).

| \( x_i \) | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 |
|-----------|----|----|----|----|----|----|----|----|
| \( f_i \) | 7 | 3 | 8 | 5 | 6 | 8 | 4 | 9 |
