Introduction

Mayfield High School- Statistics Coursework

In this coursework I am going to investigate the relationship between the height and weight of girls and boys in year 11 at Mayfield High School. I will choose a certain number of boys and girls from the data provided and develop my own data to prove or disprove my hypothesis.

I will start by choosing a certain number of boys and girls from the data. There are 170 pupils in year 11, 86 are girls and 84 are boys. I am not going to compare all the girls and boys in year 11 as that would be too many, so I have to work out a suitable number for each gender. I want to

As you can see, the average height for boys is 1.7m and the average weight is 60kg. The girls average height is 1.6m and their average weight is 50kg. This shows that my hypothesis is right.

As you can see from the pie charts, again my hypothesis is true, the taller boys get the heavier they are compared to girls.

I have collected quite a lot of data and it all proves that my hypothesis is true. There are some exceptions to the rule but generally as boys get taller they weigh more than girls.
