To test the effect of a medication, 100 volunteers were randomly divided into two groups. Each person was given a month's supply of pills. For one group, the pill contained the medicine, whereas for the other group, the pills contained only inert ingredients. Participants were not told which type of pill they had. At the end of the month, a researcher evaluated them to determine if they had improved. The researcher did not know which of the subjects had the pill with the medicine added.
