Hypothesis: antibiotic b is better than the currently-used antibiotic a. Control group: subjects with ulcers receive a placebo (a pill that contains no medication: the two test groups each receive one of the antibiotics. Double blind study: neither the doctors nor the patients know which group they are in. Large number of patients assigned randomly to 3 groups: control group: subjects with ulcers receive a placebo (a pill that contains no medication, the two experimental groups: each receive one of the antibiotics. Random assignment of many participants reduces differences in age, weight, gender & other factors that might affect results. Placebo ensures that control group has same sensory experience and expectations as other groups. Collect data: endoscope inserted into stomach used to detect ulcers.
