Data-Handling Project

Data-Handling Project

Introduction

Mayfield High school is a secondary school for pupils age 11-16. I

will be doing a data-handling project and have been asked to

investigate the relationship between height and weight of 30 random

students of year 10 and 11. This includes boys and girls.

Hypothesis

==========

My hypothesis is that the taller the students the heavier the person

will weight. My reasons for choosing this is because I hear a lot of

people saying that this statement is correct and want to find out

myself. I have also thought a few things, which can affect the

relationship between height and weight. This includes gender and age.

Over my investigation I will be finding new hypothesises for the

weight and height relationships.

Plan

====

What I will be doing is I will collect 30 random pupils including boys

and girls. 30 Is a reasonable amount because too much will cause my

graphs very difficult to work on. I will make sure my random 30 are

not biased because I will use the Rand button on my calculator. Here

are the results I have been returned:
