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.
