MEDIAN

Order values from least to greatest

Find the middle value

*IF two values are in the middle, add them and divide by 2 to find the median!*

EXAMPLE: HOW TO FIND THE MEDIAN

Multiple Choice

What is the median?

• The number in the middle when the numbers are in order from least to greatest.

• The difference between the largest and smallest number.

• The average

• The number that appears most often.

Multiple Choice

When finding the median, what do you do if there are two middle numbers?

• Add them together and divide by 2
• Write them both as the answer
• Give up
• Pick one

Multiple Choice

What is the median of the following numbers

MEAN

• The MEAN is the AVERAGE. You find the AVERAGE by adding up all the numbers and then divide by the number of numbers.
