Range

The term you are referring to is called the range. The range is calculated as the difference between the greatest and least numbers in a set of data. To find the range of a set of numbers, follow these steps:

1. Start by listing all the numbers in the set.
2. Identify the greatest number in the set. This is the largest value in the given data.
3. Find the least number in the set. This is the smallest value in the given data.
4. Subtract the least number from the greatest number.
5. The result of this subtraction is the range, which represents the difference between the greatest and least numbers in the set.

By following these steps, you can determine the range of any set of data.
