Methodology

Sampling process

Number of subjects: 40

Target population: NYP students

Sampling process: Purposive sampling

Venue: Classroom H504

Time: Done in one session, in approximately 3 hours

Reason for choosing purposive sampling:

Purposive sampling was chosen as we required our candidates to fulfill our criteria.

The criteria are:

1. Participants must not be suffering/have suffered from any upper limb or lower limb injury in their life.
2. Participants must be between 20 to 30 years old.

Data collection

For our data collection, two measuring tapes, of length 60 inches each, were used.

Measuring tape calibration

The measuring tapes used in this experiment are meant to be used for sewing. They are soft and flexible.

The measuring tapes were compared side by side to ensure that the measurement units were identical and that they were not altered by wear-and-tear, stretching and other events that could have altered the measurement units.

The two measuring tapes are identical in their measurement units.

How we went about collecting samples

We chose Classroom H504 as it was spacious and have more floor space to conduct the research. There were no chairs or tables that were restricting us. The classroom also required students to remove their shoes before entering. This made it more convenient for us and the participants as they would not be held up at the foot measuring station.

For our chosen subjects, we

1. Explained to our subjects of our motive and answer any doubts that they might have
2. Get their consent and their age
3. Two person to measure the foot length and two person to measure forearm length
4. One person to record all the lengths

Things we used during the data collection:

1. Two measuring tapes
2. Scotch tape
3. A table and chair for participant to sit while taking measurement of forearm
4. Rulers to act as an endpoint of measurement

Set-up for data collection:

1. Tape one measuring tape on the floor, starting from the edge of the wall
2. Set up a chair and table next to the wall. Participants will have to push their elbows against the wall.
