In a cohort design, the groups are defined based on a common exposure, experience, or event (such as being born in the same year). This is different from other quasi-experimental designs where groups may be based on other factors such as matching or random assignment. Cohort designs are often used in observational studies to examine the associations between exposure and outcome over time.
