What is the median?

The median is the middle of a list of numbers.

 

Example:

Here is a list of numbers: 15, 6, 9, 23, 2

Step 1: Put the numbers in order from smallest to biggest:

2, 6, 9, 15, 23

Step 2: See which number is in the middle position.

2, 6, 9, 15, 23

Number 9 is in the middle. 

The median of this set of numbers is 9.
