Introduction

Data Handling Project

Introduction:

I am going to be investigating the height, weight, gender and age/year group of pupils from Mayfield High School, the name of the school has been made up but the data is from a real school. I have randomly selected my data and I have put it in a spreadsheet, I have only looked at years 7, 9 and 11, this will give me a lot less data and should give me some varied results.

Middle

Hypothesis:

As their age increases both girls and boys will grow in height and weight, but overall in each year the boys will always be taller.

Plan:

1. I will collect the data and take systematic samples.
2. I will draw frequency polygons to compare distributions

Conclusion

I will work out all the averages for both gendersI will draw stem and leaf diagrams for both genders, so I can do the averagesI will draw cumulative frequency diagrams because I will then be able to find the median, the quartiles and the IQRI will do box plots for both genders, so I can compare distributionsI will analyse my data.I will write my conclusion, which will say if I proved my hypothesis correct or incorrect.
