Everything you need to know

WE are woo-man hatched on the year 2009. We like to study relationships between different variables. 5 of us have to work very hard for quests that are given to us. These statistics quests is our staple food to help us to grow. We have just conquered one research recently! Enjoy reading them.

A form for us (researchers) to record every readings we took for our subjects



Jayanthi explaining on the purpose of the research to our samples





Mei Yu is telling the subject to place her arm on the '0' of the dual ruler.




Hazelina is jotting down the measurements.



Now, the measuring of subject's feet.


Our next subject (:



Feet measurement.

Mei Yu - Through this research, I get to explore more on the statistics which can be that useful even in our daily lives.

Jiuyin - I feel like my interest in statistics has deepened, throughout the course of doing this project.

Nichole - I learnt about how the flow of a research goes about and the importance of SPSS programme.

Jayanthi - Even though I may not be using statistics in my future career, I'm glad that I'm given the opportunity to be part of this project

Hazel - I learnt the importance of statistic being used even in the medical field.

Coding
Sex
1.00= Male
2.00= Female





Data Type
Age: Scale
Gender: Nominal
Forearm: Scale
Feet: Scale

















From the table, pearson's correlation coefficient of 0.909 indicate a very strong relationship between length of feet and forearm.


The final statement result - CONCLUSION

There is a POSITIVE, SIGNIFICANT ASSOCIATION between a person's length of feet and length of forearm (r=0.909, p<0.05, N=30)
Thus, WE CAN SEE IT SUPPORT OUR HYPOTHESIS (H₁).

Step #1. Take dual ruler and separate them, using protractor to ensure
that they are 90 degrees apart




Step #2. Tape down the dual ruler on the table to ensure it does not
move




Step #3. Place forearm on the right of the dual ruler, with the ‘0’ cm
marking at the distal end of the table’s edge






Step #4. Take another ruler to read the reading of the forearm from
the dual ruler






Step #6. Do this for each forearm twice






Step #7. Use same method to measure length of feet, with dual ruler
on the floor

How was data collection done ?

• Our samples range from 17 years old to 31 years old
• We explain and ask permission to our samples the reason of
taking their body parts length and we thank them for their help
• We all went to take our family, relatives and friends’ size of the
forearm and the feet length
• We ask them to straighten their forearm and place it on the table.
and rest their legs on the floor


How did you gather the samples ?

• Respondents need to take off their foot wears and socks, remove
accessories on both hands
• Ensure good lighting
• Respondents should be sitting on the chair and rest his/her
forearm on the table and the feet lie flat on the floor
• Ask the respondents to straighten their forearm and feet
• 1st measurements are taken from the wrist of the hand to the elbow
• 2nd measurements are taken from the 1st toe to the heel of the feet
• Take each measurements from left and right upper and lower limbs
• Total of 8 measurements from one person (2 on each limbs)
• Record readings on the form
• Obtain the mean of the measurements for forearm and foot length


What did you use to measure ?

• Three 30 cm rulers are used for the measurements of our respondents’
forearm and feet


How often ?

• After measuring left forearm and foot twice, we proceed to the right ones
• After we gathered 2 sides of measurements, take the average of the readings


Any rejections?

• There were no rejections
• Respondents are co-operative and willing to help us in our research
• Just that some were shy and dare not let us take their photograph of their faces, thus, only feet and forearms were taken

We found an article which says that extended arms' length is equivalent to the vertical height of a human being from head to toe. This article inspired us to find out whether the length of a person's forearm is of same length as the foot.

Importance of study
1. For convenience of buying shoes when removal of shoes is inconvenient (when you're wearing shoes with shoelaces)

2. For purposes of instructing painters when painting body parts - length of forearm is proportionate to length of foot (That is almost the same length)

Rationale - why did we choose those variables ?
We wanted to check if length of forearm is related to the length of foot, since we were always told that they are.


Research Question
Is there a significant, positive relationship between the length of forearm and the length of foot?

Null Hypothesis (H₀)
There is no significant, positive relationship between length of a person's forearm and length of foot.

Hypothesis (H₁)
There is a significant, positive relationship between length of a person's forearm and length of foot
