Introduction

Mayfield High School

Statistics Coursework

Introduction

In this assignment I will be aiming to determine whether there is a connection between IQ and Key Stage 2 results. To establish whether there is a relationship between IQ and Key Stage 2 results I will be analysing data collected from Mayfield High School. I can be satisfied that the data I have been given is reliable because although Mayfield High School is a fictitious school the data provided is based on a real school. I do realise that human error while presenting the data could lead to some information being incorrect but I am content to use this data. I will rule out any anomalous data if it becomes obvious.

 I will be using random sampling of my selected strata which is both year 8 and year 10. I have chosen to sample years 8 and 10 because then I will get a range of data from across the school. By choosing to sample data from two different year groups I will be sure that any findings I make will not just be relevant to one particular year group. I will also separate these year groups into a number of different strata. For example I will also look into the gender of the students in the sample.

I will be presenting the data that I will collect in a variety of ways and these include scatter graphs, box plot and whisker diagrams, bar charts and cumulative frequency graphs.

Conclusion

Conclusion

I am now going to state whether I accept or reject my various hypotheses. Although I cannot prove these hypotheses beyond doubt as there are limitations with my data. Firstly I am only using a sample of one school and other schools may have completely different results. Secondly I was only using a small sample of the school and if I had used all of the data provided then I may well have come up with different results. Thirdly I only sampled years 8 and 10 and if I had sampled all of the other years then I would have a more detailed and accurate set of results. Below I have stated my three hypotheses and beside them I have stated whether I accept or reject them.

Students with high IQ scores will also have high Key Stage 2 results. Accepted

Girls will have higher IQ scores than boys. Accepted

Boys will have better Key Stage 2 Maths results than girls. Rejected

I am very pleased with the outcome of this investigation as I have able to prove or disprove my various hypotheses with sufficient evidence. To extend this investigation I could have looked at the Key Stage 4 results of years 10 and 11 to see if the IQ would also be closely linked with these results. I could have used larger sample sizes and more year groups for better accuracy and reliability.

    A large number of small clusters minimises the risk of this being unrepresentative. An advantage of using this type of sampling is that it can be quick, however the disadvantage of this sampling technique is that it may not represent every single pupil that goes to that school.
