In mathematics, the mean, median, mode and range are common statistical measurements of a simple set of data. This last measurement is the determination of the length of the interval of all numbers in the data set. This calculation can be made for any set of real numbers, including temperatures. The range is a fairly easy calculation to make, and calculating it can tell you a lot about the set of numbers in question.

List the numbers in the data set of temperatures. Put them in order from lowest to highest.

Identify the lowest number in the data set, as well as the highest number.

Subtract the lowest number in the set from the highest number. The resulting value is the range of the set of temperature values.
