Range is the distance between the smallest and largest numbers in a data set (set of numerical values). When using a set of numbers, oftentimes you will be asked to find the range. All you need is a knowledge of basic math and you can find the range of a set of numbers.
Always order the numbers before solving for range. Otherwise, you may overlook numbers needed in the calculation.
Write down your set of numbers. As an example, we will use the set: 9, 8, 6, 10, 5, 4 and 13.
Order the numbers in ascending order (smallest to largest): 4, 5, 6, 8, 9, 10, 13.
Subtract the smallest number in the set from the largest number: 13 - 4.
Write down the result: 13 - 4 = 9. The range for this example is 9.
