This is GCSE right ?

So it sounds like scatter graphs, a line of best fit (if you can get one), and Spearman Rank Correlation Coefficient.

You'll probably find no correlation.

I did IQ and Exam results which had a correlation and then I could advance it by seeing correlations between gender and IQ and exam results which meant that i could use box and whisker diagrams as well.

I dont know if this is of any use but I have heard that to get the top marks you need to do strategic sampling, so maybe try that, although I didnt!
