Maths Handling Data Coursework

Hypothesis

My hypothesis is: Is intelligence related to exam results?  To do this I can investigate the relationship between IQ and Key Stage 2 results.

There should be positive correlation in the graph as above average Key Stage 2 results suggest a student should have a high IQ.

I can extend this investigation by see if there is a relationship between Sex and IQ/KS2 results.

Plan

To do my investigation I will need to collect the IQ and exam results from the Mayfield school data. I will use a sample size of 60, because it is a large enough number for a decent investigation, but not too large that I have too many people to work with. It will be fair as I will use 30 boys and 30 girls, and I am using a stratified sample so I can get the right number of people from each year and my sample is not biased.

 year boys girls total stratified sample 7 151 131 282 30 boys year 7 8 8 145 125 270 year 8 7 9 118 143 261 year 9 6 10 106 94 200 year 10 5 11 84 86 170 year 11 4 total 604 579 1183 total 30 30 girls year 7 8 year 8 6 year 9 7 year 10 5 year 11 4 total 30

This table shows how my stratified sample worked and how many people I am going to take from each year.

I am going to take my sample, and then I am going to first look at the IQ. I will draw a histogram as the data is continuous. This will help me to find out the median. I will also find out the mean, the modal class interval, and the inter-quartile range.

The main difference between the results is that there is a much bigger inter-quartile range in Year 11 than in Year 7. These results do not really support my hypothesis, as I expected the two sets of results to be quite different, with my hypothesis being that "Year 7's have higher total KS2 results than Year 11's".
