What unit of measurement do you think has been used to measure the rainfall?

Use this data to make a line graph. Your line graph must have:

– A chart title

– A y axis

– An x axis

– A y axis title

– An x axis title

You will need to analyse the graph once it has been completed and record what you have learnt from the graph in a summary. You will then be able to construct the graph on a laptop.

For your summary, think about:

– How has rainfall differed between the two years?

– Which year has had the most rainfall?

– What months had the highest rainfall?

– If you were to pick one month for the year to have the most rainfall, what month would it be? Why?

– Why is there a difference between the two years?
