Statistical Analysis of GCSE results at my secondary school summer 2010

Introduction

For my maths project, I requested for the summer 2010 GCSE Exam results from St Bede’s secondary school Exam moderator; so as to analyse it. Having received the data, I made the names of the students anonymous, to keep their information private. I kept the data in alphabetical order so that my hypothesis would make sense. I identified the gender for the 186 students that wrote the exam; which took a lot of time to get the data ready and to make it private.

I had to search on the internet for the equivalent GCSE grade points so that I could change the grades to points so as to have a good set of data for my analysis. My hypothesis for my maths project base on the GCSE result summer 2010 is the lower down you are in the alphabetical order of the registration the less you do well in the exams and by that having low GCSE results at the end, while the higher up you are in the register the better you do and having a good GCSE result at the end.

So by my hypothesis the graphs that I am going to produce base on my data results should have a negative trend (line of best fit) and for it to have a negative trend showing my hypothesis, what I did was numbered the students starting from the last student on the alphabetical order in the register numbering him/her number 1 and numbering the first student on the alphabetical order register number 186.

The table below shows what point are equivalent to each different GCSE when converted for example an A* has the point of 58 when converted, and the screen shot shows how I came about into changing all the GCSE grades into equivalent point numbers.                                          

The equivalent GCSE grade points

                 

This data is part of the main data showing just the English Language & Literature GCSE points for each student. I am going to compare the total score for each child against their alphabetical order numbering to see if we get any correlation and to prove if my hypothesis is right or wrong.

This graph is showing the grades against the Alphabetical positions base on English Language and Literature results only. The line of best fit on this graph is useless because we can’t see any correlation so the line does not make any sense which has proved that it doesn’t matter where your name is on the alphabetical list it depends on how you work hard.

This is the same kind of graph like my first (the one above)  graph but this graph is showing the grades against the Alphabetical positions base on Mathematic results only and ...
