Maths - Weight And Height Correlation

Extracts from this document...

Introduction

Introduction

I collected my data from the internet, my data is from a factious school called Mayfield high school but all the data are from real pupils.

The data consisted of name, gender, height, weight and Year group. All of the data were from year 11 and included male and female.

My investigation is hopefully going to prove that:-

  • males are taller than females in average
  • as you get taller you become heavier

I decided to collect the year 11 data because I am in year 11 also I can compare my own height and weight with the data I collected. I’m investigating this as this is a common idea and confidently I will succeed in proving that.

I have selected my data in a random style picking 20 girls and 20 boys; I chose 20 from each gender because they can represent the population of Mayfield high school. And with this data I will calculate the averages of the data for example mode, median, range. I will also put the data into dual bar charts and scatter graphs to help me to form a conclusion that can relate to my hypothesis.

Looking at the graph I worked out the following:-

Lower quartile: 42

Median: 48

Upper quartile: 56

Conclusion

 I also concluded from plan one that simply, as height increases, weight increases. This lead onto separating out the years which concluded that the amount that the pupils grew per school year increased as the year increased. Due to a school year being discreet data, I compared height to weight. However, as weight can continue to increase after a pupil’s teenage years, and from real life experience and my own knowledge, the height cannot be controlled it usually always stops and sometimes reverses. The weight can be controlled by a pupil consuming more or less which can suggest that there cannot be a fully justifiable conclusion made that can relate to everybody in the population as one of the variables can be directly controlled by a human being and the other variable cannot. However, apart from this, I can conclude that the majority of the population prove that my hypothesis is correct: as the height increases, the weight increases – it is directly proportional.

  If I was to repeat this investigation, I would choose another year to investigate, as after a few years children have grown to their typical height.
