Theoretical Framework
The established theory or set of theories a study uses to frame its problem, shape its questions, and interpret its findings.
A theoretical framework grounds a study in existing theory. It names the theory, defines its key constructs and propositions, and explains why it fits the research problem. The framework then shapes design decisions: which variables matter, what relationships to expect, and how to interpret results. It differs from a conceptual framework, which is the researcher's own project-specific model, though the two often work together.
For a thesis, a clear theoretical framework signals that the work builds on scholarship rather than starting from scratch. Examiners look for consistency: the theory introduced early should reappear when findings are interpreted, whether it ends up supported, refined, or challenged. Choosing the framework before data collection keeps the study coherent and gives the discussion chapter a ready-made interpretive lens.
