Statistics Coursework

This piece of coursework that I am doing is look at relations between height, weight, gender and Body mass index of Mayfield High School. I will do this by taking a sample of 118 out of 1183 students. The hypotheses I have to find out are the following:

. Boys are taller than girls

2. The taller you are the heavier you are

3. The more television you watch the larger the body mass index.

I will use the data given by my teacher and then do a stratified sample. I am doing the stratified sample so that I can get the right proportion sample for each year group. Using my calculator, I choose a random number between 1 and 10, and then go down for whatever number it is. For example, if the random number was 8 and there were 141 boys/girls in the year group I would choose the numbers 8, 18, 28, 38...38. Then I will use systematic sampling to get the right amount of people in each year group. The calculations for each year using the stratified sample are in the following:

Year 7 Girls: 131 x 118 ? 13

1183

Year 7 Boys: 151 x 118 ? 15

1183

Year 8 Girls: 125 x 118 ? 12

1183

Year 8 Boys: 145 x 118 ? 15

1183

Year 9 Girls: 143 x 118 ? 14

1183

Year 9 Boys: 118 x 118 ? 12

1183

Year 10 Girls: 94 x 118 ? 9

1183

Year 10 Boys: 106 x 118 ? 11

1183

Year 11 Girls: 86 x 118 ? 9

1183

Year 11 Boys: 84 x 118 ? 8

1183
