4.Longitudinal studies last for years; cross-sectional studies are relatively quick.

Explanation:

While a cross-sectional investigation gathers data of a specific population at a precise time, longitudinal research manages data from a particular sample over a long time.

That means that cross-sectional studies are quicker and less expensive than longitudinal investigations, which can even last for many years and are considerably costly.
