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: -A longitudinal study, like a cross-sectional one, is observational. So, once again, researchers do not interfere with their subjects. However, in a longitudinal study, researchers conduct several observations of the same subjects over a period of time, sometimes lasting many years.

Detailed explanation-3: -What is a longitudinal survey? The longitudinal survey can be defined as a research process that involves repeated observations of the same groups of people, whether that’s employees, a specific group of customers, or another audience group to see if their opinions have changed since you first collected their data.

Detailed explanation-4: -Longitudinal surveys. are those that enable a researcher to make observations over some extended period of time. There are several types of longitudinal surveys, including trend, panel, and cohort surveys.

Detailed explanation-5: -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.
