What is the mean? _______________________
What is the median? ____________________
What is the mode?

A mean is the average of the all the numbers. You add all the numbers and divide by how many numbers you add together.
A median is the middle. Arrange the numbers from smallest to largest and find what number is in the middle.
A mode is whichever number that occurs/shown the most. For example, 2 2 3 5 6 8 8 8 9 10. The mode is 8 because it occurs the most frequently. 
If there are two middlemost scores for the median, use the mean of those two scores.
Range is highest value minus lowest.
