Vitruvian man (Bivariate data)

Vitruvian Man

What is Vitruvian man? The Vitruvian Man is a drawing made by the Italian polymath Leonardo da Vinci in about 1490. It is accompanied by notes based on the work of the Roman architect Vitruvius. The Vitruvian Man, a late 15th-century drawing, is a prime example of such work. Intended to explore the idea of proportion, the piece is part work of art and part mathematical diagram, conveying the Old Master's belief that “everything connects to everything else.

Question: Do we have the perfect body proportions in this class as per Vitruvian man 

The perfect body proportions (your wingspan is the same as your height).

Plan: Some factors that need to be controlled are making sure people aren't wearing shoes this

could lead to an increase in height and will make my measurements incorrect. I may need to

repeat measurements just to make sure that they are accurate. I will also make sure that I

measure from their longest finger to the other longest finger. 

Data: My two variables are going to be height and wingspan. My data is going to be collected from

year 11 boys in L1VO.

Q: Do we have the perfect body proportions

P: Who are the participants 

V: Variables and values

R: Relationship. What are you expecting 

S: Step by step

C: Control
C: Conditions
R: Repeat

T - Trend 

D - Direction

S - Strength 

U - Unusual outliers 

Trend: Linear 

Direction: Increasing

Strength: Moderate 

Unusual outliers: 1

In conclusion, the answer to our question (does our class have the perfect body proportion) is no the class does not have the perfect body proportion. 25% (5/20) of the class does have the perfect proportions everyone else has an uneven wingspan to height ratio.
