Detailed explanation-1: -Longitudinal studies and cross-sectional studies are two different types of research design. In a cross-sectional study you collect data from a population at a specific point in time; in a longitudinal study you repeatedly collect data from the same sample over an extended period of time.
Detailed explanation-2: -The main difference is that cross-sectional studies interview a fresh sample of people each time they are carried out, whereas longitudinal studies follow the same sample of people over time.
Detailed explanation-3: -The benefit of a longitudinal study is that researchers are able to detect developments or changes in the characteristics of the target population at both the group and the individual level. The key here is that longitudinal studies extend beyond a single moment in time.
Detailed explanation-4: -Which of the following is a difference between cross-sectional and longitudinal studies? Cross-sectional studies assess people at one point in time, whereas longitudinal studies assess people over a long period of time.
Detailed explanation-5: -Cross-sectional and longitudinal study both are types of observational study, where the participants are observed in their natural environment.
