Quizplus · Accepted Answer

Cross-sectional design compares different age-groups at the same time. Therefore, differences between age-groups could create confounding variables that might pose serious problems for the interpretation of results. Longitudinal design follows the same individuals over a period of time, so it would be less affected by differences between age groups. Cross-cultural and cross-sequential designs compare different cultures or a combination of longitudinal and cross-sectional designs, respectively, and are not directly affected by differences between age-groups.
