1. Imagine that high schools in Regina are considering changing the typical school day to begin at 10 am. They believe that with the extra sleep, teenagers will be happier and more engaged in their studies. There are already four schools that are planning to change next year, so you, as the research methods consultant they hired to examine the impact of the change, are perfectly set up to conduct a quasi-experiment. Design four quasi-experiments that could examine the impact of starting school later- 1. a nonequivalent control group post-test only design, 2. a nonequivalent control group pretest/posttest design, 3. an interrupted time-series design, and 4. a nonequivalent groups interrupted time-series design For each of the four studies: a) explain how you would design the study /1 b) create a hypothetical graph of the study's results (assuming the intervention worked) /1 c) explain the strengths and weaknesses of the design in terms of making a causal claim (i.e., Why, specifically is it better than some designs but not as strong as others?)/1
