The norms are divided into two categories, namely, official norms and unofficial norms. Official Norms: These are the official and written rules such as laws, regulations, statutes, circulars and board decisions. The punishments and rewards regarding these norms are predetermined.

Unofficial Norms: These are non-written norms, and punishments and rewards are not explicitly stated for such norms. The individuals might face sanctions such as condemnation, mocking, exclusion and insults.
