For my 20 Time Project, I tested the placebo effect to see if it actually works. To do this I created 15 general knowledge questions, and gave one group of 6 people a positive feedback about the test before they took it and another 6 people negative feedback. For an example for the positive group, before the test I said, "This test is a very basic general knowledge quiz, nothing to worry about. Everyone who takes this test passes." I wanted to see if the people who received negative feedback did worse on the test than the people who received positive feedback. After testing I found that the people who received positive feedback did better, but it wasn't a drastic difference, they only did slightly better. Here is a picture of the graphs I made of my data:
As you can tell from the graph, the differences are subtle, but they are there. I think that if I had maybe taken a bigger group of people, or more questions I would have gotten a more dramatic difference in my data. So if I could do my project again that is probably what I would change.
Evaluating myself on this project, I think I did a good job. I spent my class time effectively by researching for the project, learning more about the effect so I could effectively plan an experiment around it without the use of pills like most placebo experiments are conducted, prepping the experiment (such as writing the general knowledge questions), and analyzing my data. I would give myself an A because I think I worked hard throughout this project and produced the results as well.
