A researcher is trying to develop a treatment for a new viral disease. He recruits 100 patients who have the disease and randomly assigns them to two groups (50 patients in each group). One group gets the new anti-viral drug and the other group gets an inactive placebo. He then monitors the severity of their condition for the next week by counting the number symptoms they display each day and creates a total symptom summary score.  a. What type of research design (correlational vs. experimental) did this researcher use?  b. What is the independent variable and the dependent variable? c. What level of measurement are the independent and dependent variables measured on? d. Is this a good or bad design for making a causal conclusions, i.e., that the independent variable causes the dependent variable? Be specific with what aspect of the study makes it good or bad.
