Introduction

In this project I will be investigating the heights and weights of pupils at Mayfield High School. Mayfield High School is not a real school, it is imaginary, and it has 1183 students altogether.

The distributions of the pupils in every year are below:

The data I will be working with is from the Edexcel Internet Database and it is secondary data. Every student has received this data. The data is of the fictitious school called Mayfield High School. The data they have given for each pupil is their Name, Year group, IQ, Weight, Height, Hair colour, Eye colour, Distance from home to school, Usual method of travel to school, Number of brothers or sisters, Key stage 2 results in English, Mathematics and Science.

I have preferred to use secondary data rather than primary data because it is more suitable; primary would take a very long time but it would be a higher degree of accuracy. The advantages of secondary data is it is easy to find and due to the short amount of time provided to complete this coursework it will be more suitable.

I will not be using qualitive data I will be using quantitve data. Qualitive data will place restrictions on my work as the only average that I could measure would be the mode.

I will have to ignore outliers as this will distort my data and also my calculations. It will cause averages too become to small or too large. Also as there is such a large amount of data I will not be using it all I will instead sample the population.

So not to get any bias, I will use a stratified sampling method to select people from the population. I have preferred to use stratified sampling because each group will be fairly represented and the number from each group is proportional to the group size.

I will be using a sample size of 100.

My 100 samples are:

I will investigate these following hypotheses using my sample of data:

Hypotheses

  • Year 8 females will be taller and heavier than year 8 males.
  • Year 11 males will be taller and heavier than year 11 females.
  • Year 8 males will be taller and heavier than Year 7 males but shorter and lighter than Year 11 males.
  • There is a positive correlation between height and weight.

I have chosen these hypotheses according to my experiences, general knowledge and what I have seen. Scientific research shows females reach maturity earlier than males. Also females usually have ...

There are one or two good ideas in this work but there are too many missing diagrams to make it a good piece of work. 2 stars
