Which two factors are critical in defining a group?

In the context of defining a group, interaction and influence are paramount. A group is characterized not just by its existence but by the interactions among its members. Effective interaction fosters communication, collaboration, and cohesion, which are essential for the group to function well.

Moreover, the influence that members exert upon one another shapes the group's dynamics and behaviors. This mutual influence can guide decision-making processes, establish norms, and create a sense of belonging among members. Together, these elements underscore the essence of what it means to be a group, highlighting the social component that distinguishes groups from mere collections of individuals.

While other factors, such as size, goals, or structure, may contribute to the understanding of groups, they do not capture the fundamental aspect of how individuals relate to one another within that group framework.
