Mean is the average - add up all the items and divide the total by the number of items e.g. Mean age of a group of people 12, 13, 14, 16, 18, 21

then divide this total by the number of people in your group (6) so we have 94/6 = 15.67

To find the Median, place the numbers you are given in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. Put them in order: {10, 11, 13, 15, 16, 23, 26} The middle number is 15, so the median is 15.

The mode is the number that occurs the most frequently e.g. find the mode in { 4, 7, 7, 8, 9,9,9,10,11,11} the number that occurs the most is 9 so the mode is 9

Awesome answers here by Chloe. I just wanted to add that all three are "averages" not just the mean.
