Aim

The aim of this coursework project is to investigate the heights and weights of 50 Males and 50 Females in the between the ages of 12 – 14.

Method

I was given a list of 531 names and from these names I had to choose 100 people, 50 male and 50 Females. This meant that my population for my first sample was all the males I years 8 and 9 and that my population for my second sample was all the girls in years 8 and 9. To select these names, I used a systematic selection. I chose every other person within the list. This did not result in a biased selection as all the names in the list were alphabetical so all the heights and weights would be random within my selection. This would mean that my results wouldn’t be biased.

Averages

Middle

        My Median height for my Males is greater than my Median height for my Females. This shows that although my central Male is taller than my Central Female, I still have more males of a greater modal height than my females but my Central Female has a greater weight than my Central Male. This to goes with my mean weight that the Females are heavier than the Males.

Scatter Diagram (Graphs 1 & 2)

I chose to represent my data on a scatter diagram because I can put on a trend line and show my correlation coefficient for each graph. It also helps as I have a large amount of data and the scatter diagram helps me to see the relationship between the Male and Female Height and Weight.

        My scatter diagram for my Male and Female Weight Versus Height shows that there is a very weak positive correlation.

Conclusion

Conclusion

From this evidence in this project, I can tell that the Males and Females are practically identical in their height as the Averages and the Box Plots show but the Females are heavier than the males as the Averages and the Box Plots also show. It also shows that I have achieved my aim to investigate the difference in the height and weight of 50 Males in Years 8 & 9 and 50 Females in the Years 8 & 9.
