# Definition of Range (Statistics)

The range of a data set is the difference between its highest and lowest values.

For example, the lowest value of the data set $\{2,3,7,9,1,4\}$ is $1$ and its highest value is $9$, so its range is $9 - 1 = 8$.

The highest value on the dot plot is $8$ and the lowest value is $4$, so the range of the data set represented by the dot plot is $8 - 4 = 4$.

### Description
