Answer:
Reference group
Step-by-step explanation:
Reference group are such groups that individuals use as a standard for evaluating themselves and their own behaviour.
They are such type of groups to which we psychologically identify with to which we may and may not belong but we may aspire to belong.
One don't actually have to be members of the group to which they refer.
Hence any group one looks at its members and takes cues on how to behave is reference group.
