Maths coursework on Mayfield high school

Introduction

Mayfield high school is a fictitious school with 1200 pupils. The age range goes from year 7 to year 11. It is a mixed school. My task is to analyse the data I have been given from Mayfield high school, and look at some of the key factors and relations between the pupils. The data given for each pupil is, year, birthday, eye and hair colour, gender, IQ, height, weight distance from home to school, and the method of travel to school.

Planning

 The factors I have chosen to investigate are the relation of height and weight to age and gender. To do this I will select a random sample of 30 girls and 30 boys from both year 10 and 11.  I will make a prediction. I will then draw cumulative frequency tables and graphs to show my findings I will then analyse them and come to a final conclusion and evaluation.

 Firstly I have to select my random sample of pupils to do this I will take my list of pupil data and select a number at random by throwing a dice. For example I get number X then as I am looking for females in year 10 I will start at the 4th female in year 10 and then write down every 4th female after the Xth female thus creating a random sample. In year 11 there are fewer pupils because of this I will throw a number on the dice and I will then after X choose every other of the selected gender.

I have collected my data and have written it in the table below I will then use the data to create a cumulative frequency table, and then a graph.

I have created the cumulative frequency chart and graph for the height of yr 7 girls from the chart below.

From this I was able to construct a cumulative frequency graph to help me to look at the range of different heights over this particular year group.

Now to look at the chart for the boys from yr 7 we will use both graphs ...
