Can someone share a simple example of a longitudinal study? A simple [longitudinal example](https://dataqix.com/longitudinal-research/) would be following 100 students from their first year of school until graduation. Researchers could collect information about their academic performance, study habits, attendance, and learning development every year. By comparing the collected information, they could understand how students improve over time and which factors influence their educational progress. This type of research provides a clearer picture of long-term development than collecting information from different students only once.
