A Cohort Study is a long-term research method where researchers follow a group of people over time to understand patterns, behaviors, or health outcomes. Think of it like watching a class of students from their first day of school through graduation to see how different factors affect their progress. This approach is commonly used in medical research, social sciences, and public health. When you see this term on a resume, it usually means the candidate has experience in planning, conducting, or analyzing long-term research projects that track groups of people. It's different from other research methods because it looks at changes over time instead of just taking a single snapshot.
