Calculate mean deviation from the median of the following data: Class interval: 0-6 6-12 12-18 18-24 24-30 Frequency 4 5 3 6 2

Explanation

To calculate the mean deviation from the median of the given data, we will follow these steps:

### Step 1: Calculate the midpoints (xi) of each class interval
The midpoint \( x_i \) for each class interval is calculated as follows:
\[ x_i = \frac{\text{Lower limit} + \text{Upper limit}}{2} \]
