Introduction

Mayfield High coursework  Sofia Khan 11P

Having allocated data of students from a school given a fabricated name, I will use this data to follow up a line of enquiry on.

From the data that I have there are 1200 students in the school, where 599 are boys and 601 are girls.

  Below is a chart showing how many girls and boys there are in each year group.

I also have details about each student about the following things:

Name, Age, Year Group, IQ, Weight, Height, Hair colour, Eye colour, Distance from home to school, Usual method of travel to school, Number of brothers and sisters, Key stage 2 results in English, Mathematics and science.

For this investigation I need 6 boys and 6 girls from Year 7,

                                              6 boys and 5 girls from Year 8,

                                              5 boys and 6 girls from Year 9,        

                                              4 boys and 4 girls from Year 10,

                                              3 boys and 3 girls from Year 11

For my random sample I will be using the first number of students for Key Stage 3 and last number of students for Key Stage 4. The students are shown on the next page.

I am going to investigate the relationship between the IQ and maths SATs result of Key stage 3 and Key Stage 4 students.

Hypothesis

I think that the higher the IQ, the higher the SATs result. I also think that the boys will have higher IQ and Maths SATs results than the girls overall.

Overall, the males did slightly better than the females, because their mean IQ is higher by 0.5

The females have a range higher by 16, which shows that their IQs are more varied, which will make my analysis more accurate.

Both scatter diagrams show that the higher the IQ, the higher their SATs result; this is shown because both show a strong positive correlation.

One of the Female’s points on the graph stands out from the rest. This student achieved an IQ of 69 and level 2 for her SATs, this maybe due to several reasons. One could be that the student is new to the country and doesn’t speak or understand much English. However, it could also be due to an error in the data.

    I will use a scatter graph because I want to see the relationship between the IQ and the Key Stage 2 results. If my prediction is correct there should be a positive correlation - showing that the higher the IQ results the higher the Key Stage 2 results will be.

    A value -1 will show that the graph has a strong negative correlation and a value of 0 shows it has no correlation. As it is easy to create on the computer. I am doing each year separately, so I will therefore not be sampling data for this hypothesis.
