What is described by the term "theoretical framework"?

The term "theoretical framework" refers to a structure that supports a study's concepts and interpretations. It provides a lens through which researchers can analyze their data and formulate their hypotheses. A theoretical framework is essential in guiding the research process as it establishes the foundation for understanding the relationships between variables, helps articulate the significance of the study, and situates the work within existing literature.

In contrast, the other options do not accurately capture the essence of a theoretical framework. A summary of all findings pertains to the results of a research study, not the conceptual underpinnings. A tool for statistical analysis relates to the methods used for data evaluation rather than the theoretical underpinning of the research questions. Lastly, a guideline for ethical considerations focuses on the moral principles governing research practices, which is separate from the conceptual and interpretative aspects of a theoretical framework.
