Distinguishing if a Relationship Exists or Can be Established between the Height and Weight of Students Ages 12-16
The aim of this investigation is to distinguish if a relationship
exists or can be established between the height and weight of students
ageing from 12 yrs to 16 yrs in year groups 7 to 11 in a mixed in a
boys and girls school. To execute this investigation I have to
acquire information from Mayfield School survey, this will provide me
with the relevant data which will be interrogated and analysed to
investigate the hypothesis.
Prediction
==========
The hypothesis for this investigation, in relation to the aim, is that
the taller the person the heavier their body weight for both boys and
girls. But that this proportion is different between girls and boys.
The ratio of weight to height is lower for girls than for boys. This
overall prediction may show anomalies which may contradict the
hypothesis.
Method
======
The method used in this investigation will consist of the following
processes.;
1. Firstly I will gather the relevant information from the Mayfield
survey and put the data into order for every year group by gender.
The summary results are shown in the Table 1

...ve correlation apart from
one year where we could say that we were shown negative correlation,
year 9 males did not fit the general term where we have someone that
is 1.55m tall and weights 67kg (approx) and someone who is 1.80m and
weights 42kg (approx) this results in a negative gradient.
I later went on to see if there was a relationship between every
female and every male, I found that there was stronger correlation
within female as every pupil was close and compact and there was a
fairly strong correlation within boys but still a couple of pupils did
not fit the trend.
A larger sample would provide a greater level of confidence in the
analysis as relying upon a random selection can only provide a certain
level of mathematically based confidence
