Final answer:
The value 24 represents the median of the given data set.
Step-by-step explanation:
The value 24 represents the median of the given data set.
To find the median, we arrange the data in ascending order: 19, 20, 21, 22, 24, 25, 26, 30, 38. There are a total of 9 data points, and since the number of data points is odd, the median is the middle value, which is 24.
