Experimental Designs

Assigned Readings
 DeVaus, Ch. 4, 5 & 6; Please note that the designs described on page 59, paragraphs 3 and 4 (starting with “Another form of natural experiment...”) and the retrospective design described on pages 60-61 are not true experiments. They are quasi-experiments. We will discuss them next week.

Research Reports
 Experimental Design Articles is a list of some articles that are about topics that you have indicated interest you. I have tried to select good articles, but I review these very quickly. Therefore, they may be somewhat weak in theory -- in which case you will need to figure out if there is a theoretical basis for the research. I may even have made a mistake in my hasty review and incorrectly identified the research design. So do not take this as a list of articles that are somehow "approved for review." I made the list to help you start your search of the literature, not to provide you with a short-cut to finding appropriate articles for review for the assignment.
