# 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.

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.

Spearmen's Rank Correlation Coefficient (SRCC) is a more accurate method to compare correlation. This is because it gives me one number for each sample and therefore I can indicate and compare between the samples or each year. It uses the mean of each set of data and looks at the distance away from the mean of each point.
