А.) A researcher is interested in investigating the binge drinking and its association with depression and anxiety among college students. The researcher surveyed a sample of 201 students from a small, private Mid-Atlantic college. A student engaged in binge drinking if the person has 25 consecutive drinks in < 2 hours for males and >4 consecutive drinks in < 2 hours for females. Each student answered the 7-item Generalised Anxiety Questionnaire, and a depression and anxiety score is summarized from the answers. The researcher compared the depression and anxiety score between students who engaged in binge drinking and student who did not. Which one of the following statements is TRUE about this study? This is an experiment, because the objective of this study is to compare an outcome between two treatement groups. O This is an experiment, because the researcher knows whether each subject engaged in binge drinking or not. O This is an observational study. В.) A researcher wants to do a Coca Cola/Pepsi taste test. The researcher pours a sample of Coca Cola into a cup and a sample of Pepsi into another cup. These two cups are the same but marked on the bottom. Each subject then tastes both samples and rates the taste on a five- point scale (1 = poor to 5 = excellent.) Which one of the following statements is TRUE for this study? This is a completely randomized comparative design. This is a matched pairs design, and it is a randomized block design with each brand as a block. This is a matched pairs design, but it is not a randomized block design. O This is a matched pairs design, and it is a randomized block design with each subject as a block.
