Scenario A hospital wants to evaluate whether a new type of physical therapy speeds up recovery for patients with knee injuries compared to the standard therapy. The hospital selects 100 patients with similar knee injuries. Half of the patients are randomly assigned to receive the new therapy, while the other half receive the standard therapy. The doctors and patients do not know which therapy each patient receives to prevent bias. After six weeks, the recovery progress of all patients is measured and compared.
