| Which of the following statements are true? I. A sample survey is an example of an experimental study.; II. An observational study requires fewer resources than an experiment.; III. The best method for investigating causal relationships is an observational study. (A) I only; (B) II only; (C) III only; (D) All of the above.; (E) None of the above. | The correct answer is (E). In a sample survey, the researcher does not assign treatments to survey respondents. Therefore, a sample survey is not an experimental study; rather, it is an observational study;. An observational study may or may not require fewer resources (time, money, manpower) than an experiment. The best method for investigating causal relationships is an experiment - not an observational study - because an experiment features randomized assignment of subjects to treatment groups. |
