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 middle-most scores for the median, use the mean of those two scores.

Range is highest value minus lowest.
