Answer to Question 1

RANDOMIZED EXPERIMENTS, UNLIKE OBSERVATIONAL STUDIES, OFTEN ALLOW US TO DETERMINE CAUSE AND EFFECT. IN OBSERVATIONAL STUDIES, YOU CANNOT ASSUME THAT THE EXPLANATORY VARIABLE OF INTEREST IS THE ONLY ONE THAT MAY BE RESPONSIBLE FOR ANY OBSERVED DIFFERENCES IN THE OUTCOME VARIABLE.
