Prof Rea’s Exam Q2 A researcher conducted a study to determine if an antidepressant reduces the chance of migraines. He randomly assigned 300 patients to take the antidepressant every day and 300 patients to take a placebo every day. After a certain length of time, he reported the number of migraine days in the patients who took the antidepressant every day and in those who did not take the antidepressant every day. What is the most important reason for the researcher to randomly assign patients to one of the two groups? So that equal amounts of antidepressants and placebo would be used during the experiment. So that the results of the study will generalize. So that the groups are similar, or have no real difference, prior to the treatment. So that there are an equal number of people in both groups.
