Data Handling

Mayfield High School



I am going to collect data and evidence to support (or not support) the both assumptions made by me.

To collect the data, I will have to do survey’s and questionnaires so I have enough statistics to start a piece of coursework to prove the assumptions I’ll be making. This is called “Primary Data”.

I will not be using that, instead of that I’ll be using “Secondary Data” meaning you don’t have to do surveys or ask people to fill in questionnaires regarding my assumptions for this particular coursework which will help me end with a accurate, correct and reliable conclusions; so it’s convenient and saves a lot of time.

There are also advantages of using secondary data and are:

  • Its easier, faster and cheap to acquire
  • It will probably indicate the starting point

I don’t see any harm in using it for my project since my teacher delivered me the data so it must be accurate and reliable enough to work with.

Different data is recorded for students; on a short scale it informs me their year group, gender, height, weight and their IQ of course.

Total number of students in Mayfield High School are 1183 which is a fictional school however the data based isn’t.


The line of inquiry I’ve decided to follow is “The relationship between Height

Well coming back to my first assumption I ended up with a sample size of 90 which will be easy to analyze and I will surely end up with a correct conclusion.

After finishing off with the method I used in my first step which was “systematic sampling”, then picking out my samples and recording them, I deleted the variable not needed except some which will be required for the second assumption in order to extend my investigation.

Next step I’ll be taking is drawing a “Scatter Graph”, I will clearly explain what a Scatter Graph is used for and what are needs for it in this project.

    This again shows that my hypothesis may be true. They are also very similar - girls seem to be a little shorter in some places than the boys. I'm going to do a stem and leaf diagram. Stem and Leaf diagrams make it very easy to find out the mean, mode, range and median of my results because they are set out easily.

    Therefore, stratified sampling will be helpful due to the fact that there are different numbers of students in each year, and so there is less chance of unequal representation. I will be investigating 20 boys and 20 girls altogether. I will be calculating my stratified sampling using the table that
