What type of research design involves collecting data from different samples within the same population?

• A. Longitudinal design
• B. Repeated cross-sectional design
• C. Exploratory design
• D. Cross-sectional design

Answer: (B)

The type of research design that involves collecting data from different samples within the same population is best represented by a repeated cross-sectional design. This methodology allows researchers to examine changes over time while utilizing distinct samples from the same population at various points. In a repeated cross-sectional design, researchers can track trends and shifts in characteristics or behaviors by conducting separate surveys with different individuals, but all drawn from the same population. This helps in understanding how collective attitudes or variables may evolve, while still maintaining the ability to generalize findings to the broader population. Longitudinal design, on the other hand, focuses on collecting data from the same individuals over time to observe changes at the individual level, making it unsuitable for distinguishing separate samples. Exploratory design primarily aims to investigate a phenomenon before forming a hypothesis rather than emphasizing the sampling approach. Cross-sectional design captures a snapshot of a particular population at a single point in time, involving one sample rather than multiple. In summary, repeated cross-sectional design effectively utilizes different samples to reflect changes in a population over time, making it the correct choice in this context.
