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: -Cross-sectional studies are observational in nature and are known as descriptive research, not causal or relational, meaning that you can’t use them to determine the cause of something, such as a disease. Researchers record the information that is present in a population, but they do not manipulate variables.

Detailed explanation-3: -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.

Detailed explanation-4: -Longitudinal studies differ from one-off, or cross-sectional, studies. 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-5: -Cross-sectional study design is a type of observational study design. In a cross-sectional study, the investigator measures the outcome and the exposures in the study participants at the same time.
