Mean : 16
Median : 17
Mode : 18




Explanation :

Mean :

8+9+12+12+13+13+13+15+16+16+16+17+17+18+18+18+18+18+19+19+19+19+20+20 = 383

383 divided by 24 = 15.95

Rounded : 16


Median :


8+9+12+12+13+13+13+15+16+16+16+17+17+18+18+18+18+18+19+19+19+19+20+20

There are 24 numbers here, the two middle numbers are 17 and 17.

17+17 = 34
34 divided by 2 = 17

Mode :


8+9+12+12+13+13+13+15+16+16+16+17+17+18+18+18+18+18+19+19+19+19+20+20

We see here 18 is repeated 5x, thus making it the number repeated the most.
