Answer:
Median : 15
Mean : 28
Explanation:
Finding median is simply finding the number in the middle, by crossing out each number equally by side, you will be left with 15, therefore 15 is our median.
For mean, you have to add all the numbers given, then divide them by the amount of numbers there are:
10 + 48 + 21 + 15 + 48 + 24 + 30
196
196 / 7
28
