RESEARCH METHODOLOGY

Detailed explanation-1: -A longitudinal survey is one that is created in order to gather data from respondents over a period of time. Surveys are distributed multiple times to the same group of respondents in order to study how specific variables change over time.

Detailed explanation-2: -Panel studies are a particular design of longitudinal study in which the unit of analysis is followed at specified intervals over a long period, often many years. The key feature of panel studies is that they collect repeated measures from the same sample at different points in time.

Detailed explanation-3: -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-4: -Longitudinal studies allow researchers to follow their subjects in real time. This means you can better establish the real sequence of events, allowing you insight into cause-and-effect relationships.
