observational study
- abstract:
- In epidemiology and statistics, an observational study draws inferences 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.
- This is in contrast with experiments, such as randomized controlled trials, where each subject is randomly assigned to a treated group or a control group.
