In experiments, it is important to consider the potential confounding variables, which could influence how we must interpret the causal relationship. A confounding variable is a variable that has an effect on the response variable, but was not properly controlled for in the experiment. For example, suppose a student living in a dorm wanted to do an experiment to see if offering a free t-shirt would get more people to come to his social activism club. He put up large signs on the third and fourth floors of his dorm advertising a free t-shirt and free pizza for those who attended the next meeting. He did not put up any signs on the first and second floors. He found that more students from the third and fourth did, in fact, attend the next meeting. After talking to a Statway student, he realized he could not conclude that offering a free t-shirt increased attendance, because there were confounding variables in his experiment. What are two potential confounding variables in his experiment?
