A group, in a general sense, refers to a collection of individuals or items that share common characteristics or purposes. Groups can be formed based on various criteria, such as interests, goals, or demographics. For example, a sports team is a group of athletes working together to compete in a specific sport. In social contexts, groups can influence behavior and identity. They can range from small gatherings, like a book club, to larger organizations, such as nonprofit organizations. Group dynamics play a significant role in how members interact and collaborate, impacting decision-making and social cohesion.
