Find the mean deviation about the median of the following frequency distribution: Class:, 0-6, 6-12, 12-18, 18-24, 24-30 Frequency:, 8, 10, 12, 9, 5

Explanation

To find the mean deviation about the median for the given frequency distribution, we will follow these steps:

### Step 1: Create a Frequency Distribution Table
We have the following classes and frequencies:

| Class | Frequency (f) |
|---------|---------------|
| 0 - 6 | 8 |
