For this assignment, I want you to think about an experimental question you are interested in. For this experiment (can be as real or as unrealistic as you would like), explain a possibility for every part of an experiment below: An experiment in which I am trying to find out how much a placebo affects the performance of athletes. I will have two groups in my experiment, and tell one of them that they are receiving caffeine pills (group A) to help their performance in their sporting event that day. The group that I told they would receive caffeine pills will receive a sugar pill, giving the placebo that they are more likely to succeed because they have had caffeine. The other group will not receive any pil (group B) l, and compete as normal. I will use my data collected on how each athlete from each group performs, and use it to find out if there is a working placebo effect that enhances the performance of athletes who took the pill, which makes them perform better. Explanatory variable: The athlete's reaction to the possible placebo effect. They will be given a sugar pill and told they were being performed enhancing caffeine pill. I will be measuring the change in their performance, and seeing if the fake caffeine will make the athletes perform better, compared to the group that did not receive any fake pill, and also had no placebo effect. Response variable: Giving group A a fake pill, to test their reaction, and see if their performance is enhanced by a placebo effect. Are there any confounding variables: I think there are many. How much sleep did all of the athletes get which might affect their performance, and how good is each athlete usually? If I accidentally put the top player in one group, and a really bad player in another, the result might become biased. Do my athletes have pre-existing opinions that might change their reaction to the placebo effect? For example, maybe some of my athletes think that caffeine makes them too hyper to focus on their sport, so before I give them the fake pill they might already assume that the pill will make their performance worse than normal. Control group: My group that is unchanged from normal, group B, the one that is not given any drug, or fake drug. They will be competing as they normally do to help me contract with group A.
Will there be a placebo? Why or why not? Yes. I am bliding group A, and telling them they they are receiving caffeine pills, which might make them perform better. With this, I will see if their performance changes depending on their belief that they had caffeine or not. Lying to them might give them a placebo effect. Will there be any blinding? Yes. I explained above Will this be an observational study or a survey? Yes, I am watching the player's reactions in group A, and seeing if their performance changed because they think they've taken a caffeine pill. I am watching someone's reaction to something in my study which makes my study an observational study
