GCSE Mathematics Coursework

Aim

The aim of this investigation is to distinguish if a relationship exists or can be established between the height and weight of students ageing from 12 yrs to 16 yrs in year groups 7 to 11 in a mixed in a boys and girls school.  To execute this investigation I have to acquire information from Mayfield School survey, this will provide me with the relevant data which will be interrogated and analysed to investigate the hypothesis.

Prediction

The hypothesis for this investigation, in relation to the aim, is that the taller the person the heavier their body weight for both boys and girls.  But that this proportion is different between girls and boys.  The ratio of weight to height is lower for girls than for boys.  This overall prediction may show anomalies which may contradict the hypothesis.

Method

The method used in this investigation will consist of the following processes.;

  1. Firstly I will gather the relevant information from the Mayfield survey and put the data into order for every year group by gender.  The summary results are shown in the Table 1

Conclusion

For all the females from years 7 to 11 had either positive correlation or no correlation at all, girls tended to follow the general idea that the taller you are the heavier you are.

For all males from years 7 to 11 had positive correlation apart from one year where we could say that we were shown negative correlation, year 9 males did not fit the general term where we have someone that is 1.55m tall and weights 67kg (approx) and someone who is 1.80m and weights 42kg (approx) this results in a negative gradient.

I later went on to see if there was a relationship between every female and every male, I found that there was stronger correlation within female as every pupil was close and compact and there was a fairly strong correlation within boys but still a couple of pupils did not fit the trend.  

A larger sample would provide a greater level of confidence in the analysis as relying upon a random selection can only provide a certain level of mathematically based confidence

All my work was carried out using Microsoft Word and Excel.

  1. Maths Data Handling

    The standard deviation for the heights of boys in the whole school was 17.37 cm, whereas the standard deviation for the heights of boys in year 7 was 7.72 cm. This means that the standard deviation for the boys representing the boys in the whole school was twice as much
