Math’s Coursework Statistics Planning Investigation I have been given a survey of the Boy’s of the Oratory School. The survey consists of the boy’s pulse, height and weight. I have made two hypotheses: 1. The lower the pulse, the taller you are. 2. The taller you are, the higher your weight is. My reasons behind hypotheses 1 is because the lower your pulse normally means you are fit and sporty, most sporty people are reasonably tall. My reason behind hypotheses number 2 is because you are bigger and therefore should have a reasonable amount of weight compared to someone who isn’t that tall. Method I will be choosing 28 samples at random. This is to show that my data isn’t biased. I have picked people from high pulse, weight and height and I’ve also have picked people with a low weight, height and pulse. I haven’t manipulated the data at all. The survey was taken on a Thursday morning. Results Below are the samples that I have chosen at random. The data is raw.
