Statistics Course Work

Mayfield School Project

Form 5 – Salesian College


Year 11 Mayfield Statistics Coursework

Introduction:

In this investigation I shall be investigating the relationship between the height and age of random group of girls and boys taken from Mayfield School. The years, which I will be comparing, are from year 7 to year 11. I will also be comparing the weight and height of these children. Because there is a massive bulk of information collected from every child in the school in the selected age groups I have had to choose 60 random samples of people from the school. I worked out how many people I needed from each year and from they’re got the amount of random people I needed from each year. They are random to insure that there can be no fixing in the results. So this means that every person involved will have the exact fair chance of selection as the others.

When I have the correct information I need about the 60 students that I have chosen at random I will then analyse the information. I will proceed in doing this by first making scatter graphs for each of the students in each year, then I shall make bar graphs and make averages of each year then a final average of every person selected for both aims.

Conclusion

But it seems my prediction that if a person is below their average height in the class and gender then they will most likely weigh more, was wrong. My results show a lot of the smaller people seem to be of average or slightly lower or higher weight.

Finally my other prediction has been proved correct that the older the selected person gets the taller they will get.

Evaluation:

If I were to redo this experiment then I would most likely change the following things:

I would go over and check more precisely the random numbers I have been given and make sure the info I take from the numbers of the people given are correct.

I would also try and make more graphs to make more sense to what I am trying to explain and use practice graphs to help explain.

Also I would try and use more information so I can get more predictions i.e. choose different variables to compare.

If possible if I did try and re-do the experiment I would try and use a higher amount of samples so I could try and get a more accurate result so instead of using 60 samples I would use 100 which could prove to me more efficient.

I would also try and put more information about each person randomly chosen.

    I will then do the same with the girls and compare them using box plots. Finally I will compare the boys with the girls. I will start by taking a stratified sample of the different year groups. I will be taking a sample of 10% of boys and girls from years 7 to 9.

    If the hypothesis will be true, the relationship will be most reliable when using only KS4. I have decided to take 20% of each year group. I will also make sure that my investigation will consist of the proportional amount of males and females.

    Correlation Coefficient A correlation coefficient is a number between -1 and 1 which measures the degree to which two variables are linearly related. If there is perfect linear relationship with positive slope between the two variables, we have a correlation coefficient of 1; if there is positive correlation, whenever one variable has a high (low)
