My main factor I am investigating is going to be weight. For the
majority I aim to investigate the effect of weight on height. I am
also going to look at the frequency of different weight groups among
A· The height will be measured in cm. I will keep it continuous by not
asking the people to place their heights into groups, but instead
enter their heights.
This will be Quantitive data.
A· The weight will be measured in cm. I will keep it continuous by not

A· I will collect this data myself.
I predict average height people weigh the least, followed by smaller
people, who weigh more than usual, and lastly the taller people will
weigh the most.
I think smaller people will weigh more than average because people who
stay indoors and don’t get as much exercise (to burn the calories) put
on weight, and don’t grow because they don’t get enough exercise.
Taller people, I think will weigh the most because they will have more
mass to make up for them being tall (for example imagine cubes,
you stack the cubes up to make a taller cube which has more mass than
the individual cubes).
Although greatly exaggerated the graph shows what I mean.
I predict that the average height will be or a range 150cm, 160cm
for Year 7 and Year 8 Girls and Boys. I have predicted this because my
own height is 165cm and I know my height doesn’t fluctuate wildly, and
that I ‘t grown much since Year 7 and 8, so I took away 10 cm
which left me with 155cm A±5cm.
I also predict that the average weight will be over a range of 45kg,
50kg for Year 7 and Year 8 girls and Boys.
I have predicted this
because I know I was about 48kg in Year 7 and Year 8 and weighed about
