Summary: The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
The equation used to find the range of a data set is maximum value - minimum value = range.. To find the range of the data set given as 5, 7, 9, 1, 11, 4, 8, 5 and 12, one finds the minimum value of the data set as 1. The maximum value is 12. By subtracting these two values, the range is 11, or 12 - 1 = 11..
