The cross-sectional method is more common than the longitudinal method because it provides results relatively quickly and is generally less expensive than the longitudinal method. The longitudinal method requires observing the same group of individuals over an extended period of time, which can be costly and time-consuming. The cross-sectional method allows researchers to compare different age groups at the same time, providing insight into age-related differences without the need for prolonged observation.
