Median = Middle number
Directions: Arrange numbers from greatest to least OR least to greatest, if there is an odd number of numbers in data, choose middle number; if there is an even number of numbers in data, then take the mean (average) of the two middle numbers (add two middle numbers then divide by two).
Mode = Most (The number that appears most often)
Note: There is no mode if no number appears most often.
Range = Largest number minus smallest number
