Observational study designs, also called epidemiologic study designs, are often retrospective and are used to assess potential causation in exposure-outcome relationships and therefore influence preventive methods. Observational study designs include ecological designs, cross sectional, case-control, case-crossover, retrospective and prospective Observational Study Designs: Cohort study Cohort studies can provide the highest level of evidence, out of the observational studies, regarding the relationship between exposure and outcome. 2013-10-14 · Observational study designs include ecological designs, cross sectional, case-control, case-crossover, retrospective and prospective cohorts. An important subset of observational studies is In fields such as epidemiology, social sciences, psychology and statistics, an observational study draws inferences from a sample to a population where the independent variable is not under the control of the researcher because of ethical concerns or logistical constraints. One common observational study is about the possible effect of a treatment on subjects, where the assignment of subjects into a treated group versus a control group is outside the control of the investigator An observational study is research whereby variables are beyond the control of researchers.

A prospective study identifies individuals and collects information as events unfold.For instance, medical researchers may identify and follow a group of similar individuals over many years to assess the possible influences of behavior on cancer risk.
