Range

If we have a set of values, the range is the difference between the largest and smallest values in the set.

Calculating range

\text{range} = \text{largest value} - \text{smallest value}

Examples

Find the range of \{2, 3, 5, 7, 11\}

• \text{largest value} = 11
• \text{smallest value} = 2
• \text{range} = \text{largest value} - \text{smallest value}
• \text{range} = 11 - 2
• Answer: \text{range} = 9

Find the range of \{1, 4, 9, 16, 25\}

• \text{largest value} = 25
• \text{smallest value} = 1
• \text{range} = \text{largest value} - \text{smallest value}
• \text{range} = 25 - 1
• Answer: \text{range} = 24

Find the range of \{3, 1, 4, 1, 5, 9\}

• \text{largest value} = 9
• \text{smallest value} = 1
• \text{range} = \text{largest value} - \text{smallest value}
• \text{range} = 9 - 1
• Answer: \text{range} = 8
