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

06

94

200

84

86

70

Total

90

80

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.
