Final answer:
A small group is a collection of people who interact to accomplish shared goals and can include dyads or triads. These groups have strong cohesion and alignment of identity among members.
Step-by-step explanation:
A small collection of people whose members interact with one another, usually face-to-face, over time in order to reach goals is called a small group. This concept refers to any collection of at least two members who interact with some frequency and who share some sense that their identity is aligned with the group. They could be in a formal setting like a project team or a more casual one like a circle of friends. Small groups often experience strong internal cohesiveness and a sense of connection.
Examples of small groups include a dyad, which is a two-member group, a triad, which is a three-member group, and nuclear families. The dynamics within such groups are intimate, and relationships are close-knit. While small groups may face challenges when trying to achieve large goals, they can be quite effective due to their tight connections and common purpose.
