Quizplus · Accepted Answer

A cross-sectional study compares different groups of individuals at one point in time. In this case, the researchers are comparing the performance of different age groups on the SAT at one point in time. A cohort study would follow one group of individuals over time, while a longitudinal study would measure changes in a single group of individuals over time. The Flynn effect refers to the increase in IQ scores observed over time, and is not directly relevant to this question about SAT performance.
