...college women’s mental health, specifically, how much does coffee help a student’s productivity? Ideally, I would want to conduct an experiment, so that I could have causational conclusions instead of unknown associations. From a large university, I would ask women from different majors, who regularly drink coffee and some who do not, to participate in my experiment. I would ask them (n=20) to do a series of academic based tests covering basic material in math, history from a lecture, English writing, and science. Including multiple academic areas would reduce the variability because of someone’s major. I would ask two women from ten different majors and ask them to take these series of tests with on drinking caffeinated coffee and the decaffeinated coffee, the placebo. I would compare the test results to the women in the same major to each other in a paired t test.
