Mean:
Add up all the numbers and divide by the total number of numbers:
(12 + 23 + 17 + 20 + 14 + 14 + 18 + 16 + 17 + 18 + 18) รท 11 = 17
Median:
First, put the numbers in order from least to greatest:
12, 14, 14, 16, 17, 17, 18, 18, 18, 20, 23
The median is the middle number, which is 17.
Mode:
The mode is the number that appears most often. In this set, 18 appears three times, which is more than any other number. So the mode is 18.
