INTRODUCTION

Welcome to the first blog posting of Sub-group 4.

In this post, we will be introducing to you:
- Our research topic
- The reason behind why we chose this topic
- Independent and dependent variables
- Null and research hypothesis
- Supporting literature review of chosen topic
- Application to our context



Our statistics topic is based on Leonardo Da Vinci's Study of Human Proportions which was made famous by his drawing, the Vitruvian Man.


Traditionally, the human body is represented as being 8 heads tall:

1)From the top of the head to the chin
2)from chin to the nipples
3)from the nipples to the navel
4)from the navel to the crotch
5)from crotch to mid-thigh
6)from mid-thigh to just below the knees
7)from below the knees to the middle of the tibia
8)from mid-tibia to the feet

The wing span or arm span of both arms outstretched is also equal to a person's height from head to toe, evidenced by the square surrounding the Vitruvian Man.

This theory is what we are trying to prove.

Our variables are:
- Independent: The human arm-span from tip of one hand to tip of the other hand
- Dependent: The human height from top of head to bottom of ankles

Our null hypothesis:
There is no relationship between a person's arm span and his height

Our research hypothesis:
There is a relationship between a person's arm span and his height

This is based on our literature review of a research we have found on arm span and height which was proven positive, meaning there is a positive relationship between the two variables.

The importance of our study is to find out the natural height of a person through his arm-span and how his height can change throughout his lifetime due to pubertal growth spurts, spinal deformities, growth deformities or the natural process of aging.
