The answer is 16. To calculate the range of a set of measurements you are calculating the difference between the highest number and the lowest number. So in this set of measurements the highest number is 31 and the lowest number is 11. To find the difference between numbers, you have to subtract them. If we subtract 11 from 31 we get 20. So, with that being said the range of the following set of measurements is 20.
