Data Handling Coursework

Introduction

I plan to perform an investigation to find out if there is a relation between height and shoe size. I chose this investigation because my friends told me there is no relation between height and shoe size and with this investigation, I can prove them wrong. I shall do this investigation by randomly asking thirty boys and thirty girls for their height and shoe size. This is simple and there will certainly be no bias involved. I will then create a table of results and enter my readings into it. I will then create bar charts, histograms that will make the data more clear. Then I will create a scatter diagram, which will show me if there is correlation between people’s height and shoe size.

I believe the table above is a good table to use because it is immensely easy to read off and it is also easy to enter the information.

Looking at my histogram, I can draw the conclusion that height definitely has a relation to show size for boys and girls.
As we can see from my scatter diagram, there is a strong positive correlation between boys’ shoe sizes and heights and weak positive correlation between girls’ height and shoe size. Why is this? Why is there a strong positive correlation between boys’ height and shoe size and only a weak correlation between girls’ height and shoe size?  I believe this is because the results I collected were unusual and if I had carried out an investigation where I asked the whole country, the correlation between girls’ height and shoe size would mirror the correlation of boys’ height and shoe size. However, without actually conducting this investigation and providing concrete evidence, I have no appropriate reason to believe this.
