Question

Quizplus · Accepted Answer

It is generally more difficult to draw causal conclusions from an observational study because such studies do not involve the manipulation of variables or the random assignment of participants to different conditions, which are key elements in establishing causality. Experiments, by design, control for confounding variables and allow for the establishment of cause-and-effect relationships more directly.
