"Study participants can be assigned to treatment and control groups based on their medical needs."

Explanation: Experimental studies (especially randomized controlled trials) aim to randomly assign participants so groups are comparable and to avoid bias. Assigning groups based on medical needs would be a nonexperimental/observational approach and defeats the purpose of randomization.
