What is the range of 3 7 2 4 7 5 7 1 8 8?

The range is the largest value minus the smallest value. In this case: 8 - 1 = 7, so the range is 7. Sometimes, it can be helpful to list the numbers from smallest to largest so that you can make sure you haven’t missed the values that you need by accident :)
