Longitudinal studies involve taking multiple measures over an extended period. Cross Sectional design is one of the most well-known and commonly used study designs.In this kind of study, the subset of the population or the whole population is chosen and from the selected participants, data is gathered for the purpose of helping answer research questions of interest.
