A reference group is an individual(s) or group(s) that influences the shaping of an individual’s opinion, belief, attitude, and/or behavior. There are two major types of reference groups: normative reference group and comparative reference group. Normative reference group influences an individual’s norms, attitudes, and values through direct interaction. Parents, teachers, associates, peers, and friends belong to this group. Comparative reference group refers to an aspirational group to which an individual does not belong, but is used as a standard for self evaluation.
