GCSE data handling maths coursework

Introduction:

I was given a database full of information from a secondary school. This is called secondary data because I didn’t collect it myself. I am going to compare the height and weight because I know that their bodies will go through some changes. Students are guaranteed to go through puberty some time while in secondary school. When this happens it means that the child is turning into an adult.

Hypothesis:

  1. I believe that the taller the person the more they weigh because a taller person is bigger than a smaller so they will generally weight more than smaller people.

  1. I think that there is a stronger correlation between height and weight in Y7 and Y9 because I believe that if we put the data in a scatter diagram the data for Y7 there will be not much difference but for the Y9 they will be a lot more spread out.

  1. I think growth for boys is greatest in year 9 but for girls is in year 8 because girls go through puberty before boys so they will grow before boys and boys grow later than girls so that is why boys tend to grow more in year 9 ...
