Maths GCSE Handling Data Coursework
Mayfield High School - Year 10 & 11
For my statistics coursework I am going to investigate the relationship between the height and the weight. I will use a wide range of mathematical techniques to present my data and findings in different ways. I will also focus to test my hypothesis which is: As the height increases the weight increases and also the relationship between these the height and the weight will become stronger as they get older. I also think that there will be a difference in this between the boys and the girls.
The table below shows the number of boys and girls there are in each year group:
Year Group
Number Of Boys
Number Of Girls

94
200

370
For my project I will take a random sample of 30 students. I will use the random sample button on a calculator to do this.
Year 10
No of boys: (106/370) x 30 = 8.5946 ˜ 9
No of girls: (94/370) x 30 = 7.6216 ˜ 8
Year 11
No of boys: (84/370) x 30 = 6.8108 ˜ 7
No of girls: (86/370) x 30 = 6.9730 ˜ 7
Total number of students = 31
As I just need 30 students I need to get rid of any one student
In Yr 10 boys 0.4054 is needed to get 9
In Yr 10 girls 0.3784 is needed to get 8
In Yr 11 boys 0.1892 is needed to get 7
In Yr 11 girls 0.027 is needed to get 7
Therefore it's better to get rid one Yr 10 boy to get my sample of 30 students.
