Detailed explanation-1: -Cross-sectional studies can be done more quickly than longitudinal studies. That’s why researchers might start with a cross-sectional study to first establish whether there are links or associations between certain variables.

Detailed explanation-2: -Cross-sequential designs combine aspects of both cross-sectional and longitudinal designs. They are also known as sequential, mixed, and accelerated longitudinal designs. This design is when multiple age groups or cohorts are studied over time.

Longitudinal studies are a type of correlational research in which researchers observe and collect data on a number of variables without trying to influence those variables.
