Problem 1: Identify a health behavior intervention that could be tested in a population accessible to you using an experimental study design that randomly assigns some participants to an active intervention and the remainder to a control group. Describe the specific intervention you would test and the control that you would use. Define what would constitute a favorable outcome for individual study volunteers randomly assigned to the intervention group and what measures would indicate a successful outcome in the study population as a whole. Discuss the ethical concerns that might be raised about your study plans, then explain the steps you would take to protect the safety and health of study volunteers.
Problem 2: Compare and contrast quantitative and qualitative research.
Problem 3: List and explain the two interval variables.
