Question

Quizplus · Accepted Answer

Randomization in medical experiments is used to ensure that the treatment and control groups are comparable, eliminating selection bias. The key feature of an experiment is that subjects in both groups are treated identically except for the intervention being tested, which is the "single dimension" where they differ. This allows researchers to isolate the effect of the intervention from other factors.
