To find the range of these averages we need to first put them in order which they end up looking like this

0.9, 1.71, 1.8, 2.0, 2.9, 2.9, 3.2, 3.3, 3.6, 4.0

Then to find the range you simple subtract the largest number from the smallest.

So it would look like

4.0-0.9= 3.1

Range = 3.1
Mode = 2.9
Mean = 2.6
Median = 2.9
