Maths coursework on Mayfield high school

Introduction

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, ks3 results gender, IQ, height, weight and age.

 The factors I have chosen to investigate are the relation of height and weight to age and gender. To do this I will need to take 50% of the total from each year group from both year 7 and eleven. I will then make a prediction. I will then draw cumulative frequency tables and graphs to show my results, which I will then analyse and come to a conclusion. I will come to my overall conclusion by looking at the height and weight in comparison to males ands females. I will choose 50% of the total.

 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 2 then as I am looking for females in year 7 I will start at the 2nd female in year seven and then write down every 2nd female after the 2nd female thus creating a random sample.

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 to compare the boys and girls heights and come to a conclusion of who’s taller. And how we can interpret this.

This shows that on average the ...
