What type of research involves the study of large numbers of people over time?

1. Cross-sectional research

2. Qualitative research

3. Longitudinal research

4. Experimental research

The correct answer is: Longitudinal research

Longitudinal research involves studying a large number of people over an extended period of time. This allows researchers to track changes and patterns in behavior, health, or other variables over time. Cross-sectional research, on the other hand, involves studying a group of people at a single point in time. This may not provide a complete understanding of how variables change over time. Qualitative research focuses on understanding complex phenomena and often involves small sample sizes. Experimental research is conducted under highly controlled conditions and typically involves manipulating variables to determine cause and effect relationships. It may not be feasible to conduct this type of research on a large number of people over an extended period of time. Therefore, the best option for studying large numbers of people over time is longitudinal research.
