Mean, Median, Mode and Range

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 occurring value or the most popular value.

If there is no number that appears more than once, there is no mode.

If this happens, write none for the mode

Range

This is not an average.It is a measure of how spread out the data is.

It is the difference between the biggest number and the smallest value.

The highest value minus the lowest value.
