mean, median, Mode

The mean is the average. To calculate the average, you add up all the numbers in the set, then divide by the number of numbers. Many people assume the middle number and the average are the same. However, as in the above image, one very large number can throw off the average, making it higher than the middle number.

The median is the middle number in a set. When the numbers are placed in order, an equal number of numbers fall on either side of the median.

The mode is the most common number in the set.
