Mean (Average), Median, Mode, and Range

Mean (Average): To get the mean, you add up all of the numbers in the data set and divide by the number of data points.

Median: The median is the middle number of a set of data.  If there are two numbers in the middle, you take the average of them to find the median.

Mode:  The mode is the most common number in a set of data.  If each number is listed only once, there is no mode.

Range: The range is the difference between the lowest and highest numbers in a set of data.
