Analysis of Data Between Height and Weight in Girls and Boys In my first investigation, I will be analysing data between height and

weight in girls and boys. I will also use this data to compare the

results between boys and girls as well. I will use a variety of graphs

to show this.

PREDICTIONS

I predict that as the heights increase, so will the weights. This is

because logically, the bigger you are, the heavier you are. I predict

graph will show a positive correlation and generally, boys will be

heavier and taller than girls.

I predict that both of the graphs will look like this, showing a

positive correlation:

DATA SAMPLE

The data took was STRATIFIED. This meant that the data was the right

proportion from each year. I took 60 pieces of data, 30 boys and 30

girls I divided the graphs as you can see to boys and girls. Then I

combined the graphs so that the appropriate analysis could be carried

out.
