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.

    Also I feel this trend may be since the TV helps stimulate a child mind to a certain degree and whichever program it may be it has some effect on the way a child lives there live and in my sample the effect is largely positive as I have duly come to find.

    However, there are many ways that I could have improved the investigation to better find the relationships for the variables. Firstly, instead of sampling from a small amount from a school, I could perhaps have used some government data including census information on ages, genders, weights and heights.

    at the vertical height of 3m and so they don't have to be as big as the limpets at 6m. Because the limpets are always in contact with water and so even though the volume: surface area ratio is higher, and so consequently they would have greater rates of evaporation,

  2. Is there a difference between male and female conversational styles in today's society?

    I looked at and focused on a range of relevant linguistic features, but I worked using headings and therefore if I noticed a feature that would not fit under a labelled heading, I would tend to ignore it. I feel my analysis was straight to the point and I supported and explained each point I made.

  1. Maths Data Handling

    The results that I will gain will be very reliable as standard deviation makes use of all the values. The lower the value of standard deviation, the closer most of the data is to the mean and so the results are reliable.

  2. height and weight investigation

    The most common weight (the mode) is 54 kg and again it's above the average (although this time not by a lot). The range is yet again very big but it only tells me that there's a big difference between the heaviest child and the lightest child.
