Quizplus · Accepted Answer

Longitudinal research involves collecting data from the same individuals at multiple points in time, in order to observe patterns and changes over time. This allows researchers to investigate the development or progression of certain characteristics or behaviors over time within a specific population. Longitudinal research involves studying a population or group over an extended period of time to examine changes in their characteristics, behaviors, or experiences. This approach allows researchers to track the development of the population and identify trends, patterns, or associations that may not be observable in a single snapshot or cross-sectional study. Longitudinal research can be used in various fields, such as psychology, sociology, epidemiology, education, or economics, to address complex research questions and inform policy or practice.
