Hypothesis Statement

University of Wisconsin–Madison science-writing guidance places the focused study question, biological rationale, and hypothesis together so the hypothesis follows logically from what is known and the identified knowledge gap. Hypotheses are common in hypothesis-testing empirical research but are not required in every qualitative, exploratory, descriptive, or humanities project.

Quick answer

A hypothesis statement gives a testable prediction grounded in the study’s rationale; it should follow logically from the research question and relevant background rather than appear without support.
