Social groups are collections of individuals who interact with one another and share common interests, values, or goals. These groups can vary in size and structure, ranging from small families to large organizations. Members often develop a sense of belonging and identity within the group, which can influence their behavior and attitudes. There are different types of social groups, including primary groups, like close friends and family, and secondary groups, such as coworkers or classmates. Each type serves different purposes, such as providing emotional support or facilitating task completion, and plays a significant role in shaping social dynamics and relationships.
