The range is a measure of dispersion of a set of data represented by numbers.

The range is calculated by subtracting the smallest data value (the minimum) from the largest data value (the maximum).

There is no symbol for the range in statistics.

Range = maximum - minimum

DATA: {16, 17, 10, 13, 20, 18, 13, 14, 18}

Maximum: 20

Minimum: 10

Range = maximum - minimum

Range = 20 - 10

Range = 10
