Mean, Median, Mode and Range
• Introduction

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

Averages

Mean

Sum of the values divided by the number of values there are.

Median

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

The most frequently occuring value or the most popular value.

Range

This is not an average.

The highest value minus the lowest value.
