Worksheet Overview

QUESTION 1 of 10

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"
