Finding the range

Question

Find the range of the following set of numbers:

a) 23,~27,~40,~18,~25

b) 25,~26,~57,~15,~47

a) The largest value is 40 and the smallest value is 18. Therefore, the range is 40 - 18 = 22.

b) The largest value is 57 and the smallest value is 15. Therefore, the range is 57 - 15 = 42.
