Median is the middle number- so put the numbers in order from least to greatest, and find the middle number

8, 10, 10, 15, 15, 20, 20, 20, 25, 25, 25, 35, 40

Median is 20

the range is the difference between the largest and the smallest value- 40-8 is 32

Mean is the average- add all the values and divide by the total number of values (13)

268 minutes divided by 13 days
