## Lesson: Mean, Median, and Mode

Introducing the Concept

Your students may have encountered mean, median, and mode before, but it's a good idea to review with students how to find these again. The mean, median, or mode is used by statisticians to find one number that is representative of all the numbers in a data set. Discuss with students the importance of finding one number that would be representative of all the numbers in a set.

**Prerequisite Skills and Concepts:** Students should be able to put a set of numbers in ascending or descending order and perform simple calculations using the four basic operations.

Write the following numbers on the board: 6, 3, 2, 5, 6, 14, 1, 2, 4, 5, 16, and 2.
