Range

In statistics, the range is the difference between the greatest number and the least number in a set of data.


Example

Ritchie earned the following scores in his gymnastics events:

Floor exercise: 9.4
Pommel horse: 9.7
Rings: 9.5
Vault: 9.2
The greatest number is 9.7
The smallest number is 9.2
To find the range, subtract the smallest number from the greatest. 9.7 - 9.2 = 0.5

Thus, the range in Ritchie's scores is 0.5.
