Question

Quizplus · Accepted Answer

A dyad is a two-person group, which means that if one person leaves the group, the group dissolves. This makes dyads the most fragile and unstable type of group. In contrast, a triad has three members, which creates more stability and flexibility within the group. Primary groups and secondary groups can also be stable, depending on the nature of the relationships and the purpose of the group.
