Quizplus · Accepted Answer

The best research method for this question is an experiment because it involves manipulating the independent variable (participation in one session of SAT prep course) and measuring its effect on the dependent variable (SAT scores). A survey would not provide sufficient data to determine causality and historical analysis would not be applicable in this case. Participant observation is not suitable because this research question involves objective measurements rather than subjective observations.
