The **RANGE** is not a type of average, but it is useful to know along with an average.

It simply shows how spread out the data is.

To calculate the range of a set of numbers we subtract the smallest number from the largest.

**Example**

Find the RANGE of this set of ten numbers: 5, 4, 8, 4, 3, 3, 8, 5, 1, 6

**Answer**

Step 1 The smallest number is 1 and the largest is 8.

Step 2 Subtract 8 - 1 = 7

The **RANGE is 7**

*Note that the range is ONE number, not a span such as "from 1 to 8" or "1 - 8"*
