Answer 1

18

Explanation:

1. Put them in order (15, 17, 19, 21, 24, 25, 38, and 39)

2.Then find the median, which would be 22.5

3. The lower quartile is the median of the first 4, and the upper would be the median of the upper four.

4. If it's an odd amount of number the lower would be the numbers under the median.

5. You'd get 17 and 19 so add the together then divide by 2.

6. You get 18.
