# 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.
