What is a theoretical framework?
A theoretical framework is an idea or a group of ideas that provide structure to a theory in a research study. Researchers may use theoretical frameworks to guide their studies, discover or analyze new perspectives, or find connections between seemingly unrelated concepts. Theoretical frameworks are often used in science, economics, and many other fields of study. Researchers may choose among an almost limitless variety of theoretical frameworks, but should choose one appropriate to the topic being studied and the goal of the study.
