How to measure variance in data?
Range can be used to measure variance in a data set. Range is the difference between the largest number and the smallest number. The larger the difference, the greater the variance.
Range= largest number - smallest number
Range of pages read this summer = 180 - 150 = 30
Range of pages read last summer =220 - 140 = 80
