Quizplus · Accepted Answer

A cross-sectional study compares different groups at a single point in time, which makes it the best choice for comparing the cholesterol levels of 10-year-old children and 30-year-old adults. An experimental study involves manipulating variables to observe the effect on an outcome, a longitudinal study follows the same group of individuals over a period of time, and an ex post facto study examines the relationship between variables after the fact. None of these study designs would be the best choice for comparing cholesterol levels across different age groups at a single point in time.
