The number of students in each geometry class at MHS is as follows:
20, 9, 25, 12, 15, 17, 22, 15, 23, 15
Find the mean, median, mode and range of geometry class sizes at MHS.

Mean: 17
Median: 16
Mode: 15
Range: 16

Mean:
Add up all of the numbers and divide by the total number of classes (10)
You get 17.3 or 17

Median:
To find median arrange class numbers in ascending order and find middle value, since there are 2 in the middle divide it by 2
(15+17)/2=16

Mode:
The value that appears the most, 15

Range:
Subtract smallest value from largest
25-9=16
