An herbalist interested in natural remedies wants to assess the effectiveness of the Tutsle root (a fictitious plant) in reducing fever. The investigator recruits a group of patients who have fevers and records the temperature of each person. Next, each participant is given one cup of Tutsle root tea. An hour later, the investigator takes each participant’s temperature again.
