Document Summary
Compare average levels of exposure and disease in several populations. Describe a group of individuals with a disease. Describe exposure and/or disease status in a population. Compare exposure histories in people with disease (cases) and people without diseases (controls) Compare rates of new (incident) disease in people with different exposure histories or follow a population forward in time to look for incident of diseases. Compare outcomes in participants assigned to an intervention or control group. Seek to understand how individuals and communities perceive and make sense of the world and their experiences. The approach must be appropriate for the goals of the study: example: goal is to see if an intervention is effective. Experimental design could be used: research questions that are not focused on causality. Often the best study approach is the analysis of existing data rather than the collection of new data from individual participants.
