1. Introduction

We have chosen the topic "Is a Person's BMI Related to his Height?". This study is important because height is used in the calculation of the BMI.

The variables for this research topic are:
1. Independent variable: Height
2. Dependent variable: BMI

In this research, height means how tall a person is. The unit of measurement is metre (m).

BMI means Body Mass Index. It is a tool to measure whether a person is underweight, normal, overweight or obese, based on his body weight and height. BMI is measured using the following formula:

BMI = Weight / Height x Height
(note: unit of weight is kg)

Before we embarked on collecting data, we determined the hypothesis for this study.

H0 : A person's BMI is not related to his height.
H1 : A person's BMI is related to his height.

At the end of our study, we shall see if the hypothesis is to be rejected or fail to be rejected.
