A theory is a coherent set of related hypotheses that explains and predicts phenomena. It organizes ideas about how things are connected and provides testable predictions that can be examined across different studies. Because a theory ties together concepts into a broader pattern, it guides research and practice, helping to interpret findings and anticipate outcomes in new situations. In social work, theories help explain client behaviors or social processes and offer predictions that clinicians and researchers can test with data.

Exploratory studies, by contrast, are used when little is known and aim to generate questions rather than test a framework. Descriptive studies describe characteristics or frequencies of a phenomenon without testing relationships or causality. Experimental studies manipulate conditions to assess causal effects under controlled settings. Each serves a purpose, but they do not function as an overarching, testable framework like a theory.
