For the grouped data with classes 10-19, 20-29, 30-39, and 40-49, if the mean of the grouped data is calculated to be 28, which class contains the mean?

To determine which class contains the mean, we simply check which class interval includes the value of the mean.

Given class intervals:
- 10–19
- 20–29
- 30–39
- 40–49

The mean is 28, which falls within the class interval **20–29**. Therefore, the class containing the mean is **20–29**.

2. What is the formula for the mean of grouped data?
3. How do class widths affect the mean of grouped data?
4. How can you determine the median of grouped data?
5. What is the difference between grouped and ungrouped data?

**Tip**: When dealing with grouped data, remember that the class with the highest frequency may not always contain the mean. Always check the specific value of the mean.
