1. What is the advantage of an experimental study? a. Experimental studies are less expensive to conduct than observational studies b. The researcher can eliminate bias by removing the influence of confounding factors c. The results of an experimental study are usually more generalizable than the results of an observational study d. Experimental studies identify correlation instead of causation 2. Researchers conduct a study measuring how house prices jump across school zone boundaries. They find that houses on the lower-ranking side of a school zone boundary have distinctly lower prices than houses on the higher-ranking side of a school zone boundary. This is an example of: a. An experimental study b. An instrumental variables study c. A regression discontinuity study d. A difference-in-differences study
