The range of a data set is calculated as the difference between the highest and lowest values in the set.

Given the data set: 3, 4, 4, 5, 5, 6, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 3, 3, 3, 10, 12, 12, 12, 13, 13, 15, 15, 18

• The smallest value is 3.
• The largest value is 18.

Range

$\text{Range} = \text{Maximum value} - \text{Minimum value} = 18 - 3 = 15$

So, the range of this data set is 15.
