What is the range of a set of numbers?

The range of a set of numbers is defined as the difference between the highest and lowest values within that set. This measurement provides valuable information about the spread or dispersion of the data. Specifically, to calculate the range, you subtract the smallest number in the set from the largest number, which gives you a single value that reflects how wide the data is spread out across its minimum and maximum points.

For example, if you have a set of numbers like 3, 7, and 10, the highest value is 10 and the lowest is 3. The range would be 10 - 3 = 7, indicating that there is a spread of 7 units from the lowest to the highest number. This is a fundamental concept in statistics that helps to understand how much variability there is in a dataset.
