Data Handling Coursework

Introduction

I am going to base my coursework on the Mayfield school database. I have written a hypothesis to show that my work is independent.  I intend to use the autograph package for my graphs and calculations and also using Microsoft Excel to produce my scatter graphs.  I am going to try and prove or disprove my hypothesis by using scatter graphs, Histograms and analyses.  My samples of data can be found at the back of my investigation in an appendix.

To show how strong or weak the correlation is on each graph of Ks4 boys  and girls I am going to state the R value, which will give me 95% confidence as to whether the correlation is strong or weak.  To decipher whether the R value is above or below the minimum for strong correlation I will be using a Critical values for correlation coefficient table, which can be found at the back of the appendix.

Hypothesis: my hypothesis is that

To investigate my first Hypothesis I must draw scatter graphs to compare height and weight at ks4 in girls and boys.
