Cooley coined the term for a larger, more specialized group in which the members engage in impersonal, goal-oriented relationships for a limited period of time.

Cooley coined the term Secondary Group for a larger more specialized group.

Explanation:

Secondary groups are impersonal and goal-oriented, whose main focus is to get tasks done. They take place over a limited period of time and are highly organized, often having someone overlooking the other members' tasks and general rules.

These are different to Primary groups which tend to be informal and more personal.

Cooley coined these terms in Sociology.
