5. Methodology
5.1. Pilot Testing
Before doing the test with the subjects, we decided to conduct a pilot test on our group members. This is to ensure that the process can run smoothly and further recognize the need for any improvement.
For our pilot test, we booked a discussion room in the library and had our equipments prepared.
Initially, we measured our height and arm span without leaning against the wall. We found that it was quite difficult in achieving balance and the data we took were not accurate. After a discussion, one of our members suggests that we could divide in measuring our arm span into 3 parts:
1) From the tip of the left middle finger to the tip of the left shoulder,
2) The tip of the left shoulder to the tip of the right shoulder,
3) From the tip of the right shoulder to the tip of the right middle finger.
After measuring the arm span in 3 parts, we sum up all the 3 data to have our complete arm span.
Even though it was easier to measure, the data were inaccurate as our hands tend to be unstable (we keep trembling as the strain is “unbearable’), due to this, there would always be an error.
Finally, we had a better idea amongst us. We moved the chairs away and tried to get some space. We measured our height and arm span by leaning against the wall. It was not only easier to measure, but also minimizes the error that could easily be made.
5.2. Data Collection
The focus of this study was primarily on Da Vinci’s Vitruvius’s man.
We started off by gathering in the library and briefly explain the planned procedure to the group members. There were total of five members, two members will be taking the measurements, another two will be in-charge of the informed consent and the last member will be the photographer. When all the group members have a full understanding about their assigned duty, the data collection starts.
The data collection was done using accidental sampling. We chose accidental sampling as it is more convenient and easier to obtain our data. However, accidental sampling is not representative of any group of people. The subjects of this study were chosen randomly in the school library.
Firstly, we would seek the consent of each subject whether they are willing to participate in our study. We informed the subject the purpose and procedure of our study and ensure their confidentiality would be assured. If they agree to participate in our study, they are required to sign a consent form which consists of their measurements to be taken for this study only and they did it out of free will and their rights would be protected through the informed consent.

We took the measurements once for each subject.
After the subject signed the consent form, we would start measuring the subjects’ arm span and height according to the 6 steps below:
1. Measure the subject’s arm span by standing against a flat surface and spreading his/her arms out as far as possible.
3. Tell the subject to remove their shoes and stand against a flat surface before measuring the subject’s height.
4. Measure the distance from the top of the subject’s head to the floor.
6. Record the data on the second page of the consent form. (shown in Diagram 2: Section B)
