Step-by-step explanation:
A group is a broad term that can refer to any collection of at least two people who frequently interact and share a sense of aligned identity. This may include people working together, family members, friends sharing interests, or peers in an educational setting. These groups can range in size from small dyads or triads to large groups, with the cohesiveness and potential for a majority opinion forming being distinct attributes of smaller groups.
A work team, on the other hand, is usually a small number of people with complementary skills who are committed to a common goal for which they are mutually accountable. They are not just loosely tied individuals working independently; rather, they rely on each other to achieve their objectives, and the performance of each member is significant for the team's output.
Understanding the difference between a group and a work team is key for sociological studies as it relates to human interaction in various societal contexts, including business, family, and social settings.
