wikiHow Range Calculator The range of a set of numbers is the difference between the largest and smallest values in the set. To find the range of a set of numbers, you'll need to determine the largest and smallest values in the set, and then subtract the smallest value from the largest value. Here are the steps to find the range of a set of numbers using a calculator: 1. Enter the numbers in the set into the calculator, separating them by commas. 2. Find the largest value in the set by using the maximum function on your calculator, or by manually comparing the numbers. 3. Find the smallest value in the set by using the minimum function on your calculator, or by manually comparing the numbers. 4. Subtract the smallest value from the largest value to get the range. For example, let's say you have the set of numbers 4, 8, 12, 16, and 20. To find the range of this set of numbers, you would follow these steps: 1. Enter the numbers into the calculator: 4, 8, 12, 16, 20. 2. Find the largest value by using the maximum function on your calculator: max(4, 8, 12, 16, 20) = 20. 3. Find the smallest value by using the minimum function on your calculator: min(4, 8, 12, 16, 20) = 4. 4. Subtract the smallest value from the largest value to get the range: 20 - 4 = 16. So the range of the set of numbers 4, 8, 12, 16, and 20 is 16. Page
