We define a group has two or more individuals, interacting and interdependent, who have come together to achieve particular common objectives. A group can range in size from two members to thousands of members.

A group is a collection of individuals who have relations to one another that make them interdependent to some significant degree. As so defined, the term group refers to a class of social entities having in common the property of interdependence among their constituent members.

We form self-identities through our communication with others, and much of that interaction occurs in a group context. A group may be defined as three or more individuals who affiliate, interact, or cooperate in a familial, social, or work context.

Defining a Group The term group is an amorphous one and can refer to a wide variety of gatherings, from just two people (think about a “group project” in school when you partner with another student), a club, a regular gathering of friends, or people who work together or share a hobby.
