Theoretical framework

Definition

A theoretical framework is a structure that guides research by providing a coherent set of concepts and theories that can help explain phenomena or understand specific relationships within a field. It connects various elements of knowledge and serves as a lens through which to analyze and interpret data, ensuring that the investigation is grounded in established theories.
