The Range of a data set is a measurement of how much that data set varies. Range = Largest Value - Smallest Value |

Below, we have two data sets:

1, 1, 1, 2, 4, 5, 5, 5, 6, 7, 8, 11

2, 15, 29, 30, 31, 45, 47, 50, 51, 52

The range of a data set is equal to the largest value minus the smallest value.

Range of Data Set 1 = 11 - 1 = 10

Range of Data Set 2 = 52 - 2 = 50
