I am finding the Relationship between Height and weight. My hypothesis is that the taller you are the more you weigh, There could be boys or girls in year 7 that are tall that makes them look older, or boys or girls in year 11 might be small that makes them look younger. So my hypothesis will not be perfect. I have got information from all key stage 3 and key stage 4 students. Each pupil data has different information that is not relevant e.g. hair colour, eye colour, left/right hand, favourite sport, favourite type of music etc. To prove if my hypothesis is right or wrong, I will have to do a survey. To make my survey a fair survey I will have to take a fair number of each sex, I am not going to make or rely my Hypothesis to become true, so I should not make my survey a bias survey. I would not be able to use information from each pupil in each year, so I will have to find a method to break it down, so it easier for me to do a survey, so I will find 2.5% from the females in year 7 and den 2.5% from the males in year 7, I will keep doing that the same for year 8,9,10, and 11, the answer from the 2.5% of the girls, that will tell me how many girls to survey from in that year, I will do the same for each sex in each year. I am picking random Pupils from each year for my survey; from the each gender in each year I will make a scatter graph and then do a scatter graph for each year, From the result I would be able to see if my results came true or false.

Mayfield High School-Coursework Plan

The subject of my investigation is to research the relationship between height and weigh of the students which I will select and compare different people in different year groups and see how the students relate from their height and weight. I have chosen to compare students relating their height and weight because many not only people who are taller means they will weigh heavier because people need to remember that some girls or most start growing before boys and boys start mainly later on but some boys start earlier so not many people can say that people who are taller mean they are likely to weigh a lot.

I plan to get my data of the spreadsheet which the school supplied and rearrange the order of the students in year groups and gender groups like all year 7 males then year 7 females in order etc. I plan to plot my results on a scatter graph which will show me that if the people I have chosen have either good correlation or bad correlation but also I will use cumulative frequency graphs to help draw my conclusion if really the more taller you are the more you weigh but also I ...
