Question

1. Suppose that you are conducting an experiment to test the effectiveness of three painkillers (Drug A, Drug B, and Drug C). You decide to include a control group that receives a Placebo. Thus, there are 4 conditions to this experiment. The DV is the amount of time (in seconds) that a participant can withstand a painfully hot stimulus. The data is in a file called DV. The experimenter would like to know if any of the drugs yield better results than the placebo. Analyze this data and draw conclusions.
