# Mayfield Data Investigation (handling data)

Essay by kobraHigh School, 10th grade October 2006

Intro Aims and Objectives - Hypotheses 1

During my project I will be investigating the relationship between interlinked types of data, from students at Mayfield High school. Mayfield School is a fictitious place; data on the school is available on a range of information. There is discrete and continuous data. For my first hypothesis I am trying to find a relationship between the height and weight of students at Mayfield High school. I will be collecting data from across the different age groups. Throughout my coursework I will be using the different sampling techniques stratified, random and selective sampling. With my first hypotheses I will be using selective sampling. Mayfield School is a fictitious place; data on the school is available on a range of information. There is discrete and continuous data. The discrete data includes information such as shoe size and Key Stage 2 results, where as the continuous data contains information such as height and weight.

I am going to focus on the height and weight during this investigation, as they are continuous data and produce better definitions in correlations, graphs and other results.

Hypothesis 1

The taller a student in years 10 and 11 the heavier they will be. This hypothesis will take into account two year groups and both the male and female sex.

My first hypotheses will take into two age groups and genders into account. This will provide me with a firm base to gather results from and help me to gain a sound average from across the two year groups. My first hypothesis is based upon years 10 and 11. This is because students will be more developed and the vast majority will have gone through puberty and will be approaching near full growth. I will therefore be able to gain a solid...
