Math Statistics Project My main factor I am investigating is going to be weight. For the majority I aim to investigate the effect of weight on height. I am also going to look at the frequency of different weight groups among people.

A· The height will be measured in cm. I will keep it continuous by not asking the people to place their heights into groups, but instead enter their heights. This will be Quantitive data.

A· I will collect this data myself. I predict average height people weigh the least, followed by smaller people, who weigh more than usual, and lastly the taller people will weigh the most. I think smaller people will weigh more than average because people who stay indoors and don’t get as much exercise (to burn the calories) put on weight, and don’t grow because they don’t get enough exercise. Taller people, I think will weigh the most because they will have more mass to make up for them being tall (for example imagine cubes, you stack the cubes up to make a taller cube which has more mass than the individual cubes). IMAGE Although greatly exaggerated the graph shows what I mean.

Order nowI predict that the average height will be or a range 150cm, 160cm for Year 7 and Year 8 Girls and Boys. I have predicted this because my own height is 165cm and I know my height doesn’t fluctuate wildly, and that I ‘t grown much since Year 7 and 8, so I took away 10 cm which left me with 155cm A±5cm. I also predict that the average weight will be over a range of 45kg, 50kg for Year 7 and Year 8 girls and Boys. I have predicted this because I know I was about 48kg in Year 7 and Year 8 and weighed about
