In order to study changes in answers to survey questions over time, a researcher could conduct a panel study.
A panel study is one of the longitudinal research designs. Longitudinal research is a research design that involves repeated observations of the same variable within a certain period.
In a panel study, research uses the same variables, but is carried out at different times or over a long period. These studies usually take data at a high level such as the national or country level and can have different conditions ranging from organizations, schools, households, and so on. Most of these studies are designed for quantitative analysis studies, although they can also be used for qualitative analysis studies with the data obtained.
