To find the median of a given set of numbers, you first need to arrange the data in ascending order (if it isn't already) and then determine the middle value.
The given data is: 14, 15, 19, 20, 21, 21, 22, 24, 24
1. **Arrange in ascending order**: The data is already arranged.
2. **Count the numbers**: There are 9 numbers in total.
3. **Find the median**:
- Since there is an odd number of values (9), the median is the middle number.
- The middle position is calculated as \((9 + 1) / 2 = 5\).
- The 5th number in the ordered list is 21.
Thus, the median of the data set is **21**.
Therefore, the correct response is **21**.
