Math Coursework-Mayfield High Data Handling

Introduction

In this investigation, I will be using the information provided in the Mayfield High database to carry out statistical analysis to prove my hypothesis. There are a total of 1183 students in the Mayfield High database, which is a secondary data source for my investigation. I will use some statistics skills such as standard deviation, scatter graphs, box and whisker diagrams, etc. I will carry out 3 investigations which will hopefully contribute to proving my main hypothesis. I will use 2 different year groups in this investigation, Year 8 and Year 10. I have chosen year 8 and year 10 because they represent the middle section of the school community and this is good because it will be very rare for the students to cease their body growth at that age.

Hypothesis:

The year group an individual belongs has the strong effect on their weight (The higher the year group the student belongs in, the heavier he/she is).

Sub-hypothesizes:

1. The weights of students in year 8 are relatively lighter than the ones in year 10 (main hypothesis)

2. The weights of the genders are similarly distributed
