To find the class width for the given data, we follow these steps:

### Step-by-Step Method:

1. **Identify the class intervals**: These are the ranges of social interactions in your data, which are:
   - 15-21
   - 22-28
   - 29-35
   - 36-42
   - 43-49
   - 50-56
   - 57-63
   - 64-70
   - 71-77
   - 78-84

2. **Choose any class**: For simplicity, pick the first class (15-21).

3. **Class width formula**:
   \[
   \text{Class width} = \text{Upper limit of the class} - \text{Lower limit of the class}
   \]

   For the first class, this is:
   \[
   \text{Class width} = 21 - 15 = 6
   \]

### Conclusion:
The class width is **6**.

Would you like further details or clarification? Here are 5 related questions to explore:

1. How does class width affect histogram representation?
2. How would you calculate class midpoint for each class interval?
3. What is the range of the dataset, and how is it related to class width?
4. Can the class width vary across different class intervals?
5. How would changing the class width affect the interpretation of the data?

**Tip**: Consistent class width helps maintain a uniform distribution for clearer data analysis.
