Aim

For my data handling coursework I am observing data about students at Mayfield High School. The number of students in each year varies. I have been given the data, so it is secondary data that I am using. I aim is to find the relationship between height and weight from a sample of randomly selected year 11 students. In order to aid this, I shall draw graphs to demonstrate whether or not my hypothesis is correct. Varying the types of graphs will enable me to come up with a more accurate conclusion to my results.  

Hypotheses

My hypotheses is

  1. The taller you are the heavier you are.
  2. Boys are generally taller than girls.

Collecting data required

I started of wanting a random sample of 30 boy’s and 30 girls from the huge amount of data that I had been given. I first considered writing down all the names of the 168 students in year 11 on paper, and giving them a number between 1 and 168, then picking them out of a hat. After some thought, I realised that it would take quite a bit of time. So an alternative method I used was that I gave each student a number between 1 and 168. Using my calculator, I generated a randomly made number that was within the region of 1 – 168 I was looking for. I did this by using the random number button on the calculator which gave me a random number between 0 and 1. I multiplied this number by 168 which gave me the random number I wanted.
