Longitudinal	Cross-Sectional
In this study may vary from a few year to given dicates.	In this study quick to conduct as compair to logitudinal study.
Longitudional study reguir researchers to revisite paticepant of the study at proper interval.	A cross sectionl study is conducted at a give point in time.
Logitudinal study is conducted with the same sample over the years.	In this study is conducted with different sample.
It can justify couse and effect relationship.	It can pin down cause and effect relationship.
