Cohort Definition

A cohort is a group of individuals who share a common characteristic or experience within a specific time frame. For example, a "graduating cohort" refers to all students who graduate in the same year. In research or analysis, cohorts help track trends, behaviors, or changes over time within that defined group. By studying a cohort, researchers can gain insights into how shared experiences influence outcomes, such as health, education, or social behavior, helping to understand patterns and make informed decisions.
