The Average Student Plan

Having looked at various other methods of data collection I have come to the conclusion that I will base my work on the average student. Firstly I think it is appropriate that I define what the average student actually is. There are different interpretations as to what an average student is, for adults perhaps teachers they may base their ideas as to what the average student is on exam results. Other people may believe the average student is based on what sports they play, what genre of music they listen to or what type of books they read. However for the data collection I will be carrying out I will base my data on a student’s physical attributes, as this will enable me to use higher-level maths techniques, which will be later explained.

Due to limitations in working time I have decided to focus on recording just the height and weight of males and females. I have decided to focus on height and weight because they are continuous data therefore it will be possible to apply higher-level maths techniques. Another reason for selecting this data collection is that the data is easily accessible. There are two hundred and seven pupils in my year and obtaining their measurements will not be a problem. I will hopefully have the opportunity to compare my results with the National Data from the Child Growth Foundation (1996), which my teacher has recommended we find and use because using this I will be able to compare upper and lower quartiles and the medians.

Firstly my aim is to research and discover some hypotheses about an average student using statistical techniques. The three hypotheses I have selected will be later explained

For my coursework I have the opportunity to select from four methods of sampling. Not all sampling methods will fit with my data collection as some may affect the reliability of the results. The term given to this is bias meaning if an item in a population does not have an equal selection opportunity from a sample, it is said to be bias. An example of this that I am aware of and ...
