What is Longitudinal Study?
In a longitudinal study, the same subjects are periodically examined to look for any changes that might happen over time.
In longitudinal studies, a sort of correlational research, researchers watch and gather information on numerous factors without attempting to change them.
The other social or medical sciences may also use longitudinal research, though these fields use them most frequently in epidemiology, economics, and medicine.
A longitudinal research can be conducted over any period of time as long as participants are repeatedly examined. They can last anywhere between a few weeks and several decades. They often endure at least a year, and frequently several.
