Dr. Vang was testing out a new medication used to treat depression. He had 150 participants who had varying levels of depression. Because he wanted to see whether a new drug really worked, he separated the severely depressed into one group and the mildly or moderately depressed into a second group. Then, he made sure the severely depressed group actually received the drug, while the other group received the placebo. What error, if any, did Dr. Vang make in this experiment? He should have used random assignment to groups. He should not have given any of the participants a placebo. He made no error at all. He did not have enough participants in the study
