If you want to know what score is in the 95th percentile, you would find the range (95-60=35) and divide it by 5 (since there are 5 scores in the set). Range can also be used to find percentiles. This would give you a score that is closer to the real average of the group than if you just took the average of the 60 and 95 scores. For example, if you have a set of test scores that range from 60 to 95, you would take the average of the scores by adding them all up and dividing by the number of scores. Range is often used when working with averages. For example, if you have the numbers 1, 2, 3, 4, 5, the range would be 5-1=4. It is often represented by the symbol “∆”.
Range in math is the difference between the least and greatest value in a set of data.
