Using graphs

Clear that most people recycle. No need to count!

Why use graphs?

Graphs can be read very quickly Much faster than reading the original data.

We can see patterns in the data much clearer in graphs.

How green is your sample?

Now we need to pull some useful information out of the graphs.

We need to look at the graphs and decide What was the findings from our questionnaire.

And what useful tip can be given.

Creating graphs

Using your totals you need to create three different graphs.
