The correct answer is F (False)
Explanation:
Research refers to a process used to understand, describe, analyze or predict a certain phenomenon or event. Additionally, research studies can be of different types including cross-sectional, and longitudinal studies. In the case of cross-sectional research studies this focus on studying a specific event or group of subjects in a specific period. For example, you carry a research study to understand teenagers' preferences in 2018.
On the other hand, the longitudinal study focuses on studying the same phenomenon or group of subjects over a long period. For example, you study how an individual changes its preferences from childhood to adolescence. Thus, it is false a cross-sectional research study analyzes the same group of subjects over a long period because cross-sectional focuses on only a specific time and it is longitudinal studies the ones that analyze subjects over time.
