What are an entire set of values, ideas, or attitudes shared among or learned from the members of a group?

The answer is culture.

Explanation:

Culture refers to the characteristics as well as the knowledge regarding a certain group of people. This includes aspects like language, religion, and social habits.

The Center for Advanced Research on Language Acquisition defines culture as the different models of behavior as well as interactions that are shared between people. These aspects are acquired through socialization, and in this way, we can say that culture refers to the development of a group identity according to specific social models that belong to the group.
