This worksheet is about the three different types of averages and the range of a set of numbers.

Averages

**Mean**

Add the values and divide this total by the number of values there are.

**Median**

Find the middle value when you place the values in ascending order.

If there are two middle values, find the mean of these two middle values.

**Mode**

Find the most frequently occurring value or the most popular value.

Range

This is not an average.

Subtract the smallest value from the largest. This is the range.
