Introduction

Richard Williamson 11IRO      ‘Mayfield school Course work’

I will be investigating my theory of, the taller you are the more you should weigh.

- I will use the data that has been collected from ‘Mayfield High School’; I will be using the results of 80 students in key stage 4 approximately 40 students in year 10 and 40 in year 11.

I have not chosen to sort the data by what sex you are as that is not necessary in proving my hypothesis.

Giving myself a hypothesis to test I can extend the line of enquiry which I am investigating. A hypothesis is a statement which can either be true or false, and some how shows some sort of relationship or correlation between some data. The hypothesis I plan to test and investigate to extend the investigation is as follows:

I will not be able to check the data to see how accurate it is because I will not be able to check everybody’s records. I will have to just use the more believable records.

I will use the data I have selected to see if my hypothesis is correct, I can do this by drawing graphs to show the results clearly.

The data I have selected should be enough for me to see if my hypothesis is correct.

  • The only calculations I will need to do is finding the average weight of the year 10 students, then their height and do the same for the year 11’s. By doing this I should be able to find the average weight and height of KS4 students to prove my hypothesis.

Conclusion

I did not notice anything about my results except that some of the figures where false e.g. someone weighing 9kg which is not possible.

My main conclusion is that my hypothesis is correct and that the taller the person the more they should weigh. I have found this out by using the averages.

Looking at the graph we can make some simple comments: There is a positive correlation between weight and height, suggesting that the taller the person the more they weigh. Using the line of best fit we are then able to make predictions on the relationship between height and weight. For example we could predict that a person that weighs 60 kg may be about 160cm in height.

My overall conclusion is that my hypothesis is correct and that my handling data tasks were all completed successfully.
