Explanation

To form a grouped frequency distribution using the inclusive method with a class interval magnitude of 4, we will follow these steps:

### Step 1: Identify the Range of Data
First, we need to identify the smallest and largest values in the data set.

- **Smallest value**: 10
- **Largest value**: 38
