Answer :
Longitudinal studies are often used in social sciences, public health, and psychology to gain insights into how various factors influence people's lives over time.
Longitudinal studies are research designs that follow participants over an extended period of time, typically years or even decades, to observe changes or stability in their behavior, health, and development. There are three types of longitudinal studies:
1) cohort studies, which follow a group of individuals who share a common characteristic, such as being born in the same year,
2) panel studies, which revisit the same group of individuals at multiple points in time, and
3) retrospective studies, which involve analyzing historical data from earlier points in time to track changes over a long period.
