(In the experiment we only showed one person's hand, but we tested both.)
What is is:This is an experiment that shows me which hand has a faster reaction time.
Variables of this experiment:
Variables
* The distance of the thumb and pointer finger
* The thumb and pointer finger is aligned with the 0,
* Gravity does the work for the ruler to fall
* The other person has to let go of the ruler unexpectedly.
* Non-Dominant and Dominant hand
Hypothesis
* I think that the reaction time of the dominant hand will be faster than the non-dominant hand as your right hand is used for more things.
Variables that I will try to keep the same:
* The distance of the thumb and pointer finger
* The thumb and pointer finger is aligned with the 0,
* Gravity does the work for the ruler to fall
* The other person has to let go of the ruler unexpectedly.
Sample size:
About 5! people, or 120 people, right handed and left handed. That is because if everyone was right handed, you wouldn't know about the other people who were left handed. Also, you would need 10 trials for each person.
Type of data: Quantitative
Procedure (Also in video):
1. Take a ruler that is 30 cm long and a rubber band to start the experiment.
2. Place your rubber band between your thumb and pointer finger, rubber band slightly tight.
3. Slowly take your fingers out of the rubber band , and place them right at the 0 of the ruler.
4. Your partner places their fingers exactly on top of the 30.
5. Your partner drops the ruler unexpectedly, leaving gravity to let it fall
6. The amount of cm you catch it at is your reaction time for your one hand.
7. Repeat this several times for the same hand.
8. Do steps 2-7 again for the hand you have not tested.
9. That's it!
A graph to show the results of our experiment: (video only showed doing both hands once):
and the results for my partner,
Conclusion: The reaction time of the dominant hand will be faster than the non-dominant hand.
Why: The evidence clearly showed that, since that I am right handed, and the amount of cm is lower for my right hand, my right hand has the faster reaction time.
It is the same with my partner.
