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.

 Year group Number of Boys Number of Girls Total 7 150 150 300 8 145 125 270 9 120 140 260 10 100 100 200 11 84 86 170 7, 8, 9, 10, 11 599 601 1200

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.

## Analysis of data

The whole school.

 Mean 100.5 median 101 LQ 97 UQ 104 Mode 101 Range 52

Conclusion

6

## Female of the whole school

IQ

 Median 101 Mean 100.5 Range 47 LQ 98 UQ 104 IQR 6

### 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.

This student written piece of work is one of many that can be found in our GCSE Height and Weight of Pupils and other Mayfield High School investigations section.

This relationship is that, the higher the Key Stage 2 Score the higher the IQ. From the graph I can also see that there are a few points in the graph that does not follow this pattern. These points are called outliers.

* Puberty. Pupils in KS4, are going through the process of puberty, which is extremely valid, when investigating their height and weight. Not only they change mentally, but also great changes happen to their bodies. In addition to that, there is not a specified age for girls and boys for reaching the puberty process.

This is supported by the higher median and IQR (as well as higher LQ and UQ). However, the girl's outlier has a higher value than the two that the boys have and the girl's highest value is greater than that of the boys.

Pearson's product moment correlation coefficient varies between -1 to +1. If the value is -1 it is a strong negative correlation and all points lie on the straight line with a slope downwards. If the value is +1 then the correlation is a strong positive correlation and all points lie on the straight line with a slope upwards.
