Quizplus · Accepted Answer

The researcher is comparing different age groups (1-year-olds, 4-year-olds, and 7-year-olds) at one point in time, indicating a cross-sectional research design. Longitudinal research design involves studying the same participants over an extended period of time, while sequential-cohort research design involves studying multiple cohorts over time. Age cohort is not a valid research design.
