A cross-sectional study involves the comparison of different groups or individuals at a single point in time, and this is exactly what the researchers are doing by assessing and comparing the performance of different age groups on the SAT. Factors analysis involves identifying underlying dimensions or factors that explain patterns in data; a longitudinal study involves following the same group of individuals over an extended period of time; and predictive validity is the extent to which a test predicts future performance, which is not the focus of this research. Therefore, the best choice in this scenario is A) a cross-sectional study.
