The major benefit to a sequential design is that

A) the researcher can first make cross-sectional comparisons at the same age, and then feel more confident in the longitudinal comparisons across groups.
B) the research can first make longitudinal comparisons across groups, and then make cross-sectional comparisons within groups.
C) the research can draw correlational conclusions from an experimental design.
D) selective attrition is no longer a potential problem.

Sequential Design

A research methodology that combines elements of both cross-sectional and longitudinal designs to study changes within a population over time.

Cross-sectional Comparisons

Cross-sectional comparisons involve looking at data from a population at one specific point in time to identify patterns and relationships.

Longitudinal Comparisons

A research technique that involves studying the same group of individuals over a period of time to observe changes and developments.
