Data Handling Coursework

Introduction

In this coursework I have been given the data about the weight and heights of boys and girls of Mayfield high school. I will select at random 30 boys and 30 girls from year 7 to year 11 and make a chart about the student’s heights and weights.

My Hypothesis is as follows:

The boys of year 11 are heavier then the girls in year 11.

The boys of year 7 are lighter then the girls in year 7.

The boys of year 9 there will be taller then the girls in year 9.

To prove my hypnotises I will draw bar charts, pictograms, histograms, frequency polygons, cumulative frequency graphs, box and whiskers and stem and leaf diagrams.
