Briefly discuss R I T Merton's middle range theory?

Robert K. Merton's middle range theory is a sociological theory that aims to explain specific aspects of social phenomena rather than attempting to provide a comprehensive explanation of society as a whole. Middle range theories are more focused and specific than grand theories, making them more useful for empirical research and testing. Merton's theory emphasizes the importance of developing hypotheses that can be tested through empirical research, and it has been influential in shaping the field of sociology.
