A hypothesis is a statement that what?

• A. Predicts relationships of variables.
• B. Proves a theory.
• C. Lists variables without relationships.
• D. Describes a model.

Answer: (A)

A hypothesis is a testable statement about how two or more variables relate. It makes a specific prediction or expectation about the relationship or effect you can observe in data, such as “increasing physical activity will reduce blood pressure.” This testability is what allows research to determine whether the prediction holds under defined conditions. This is different from simply listing variables without any connection, which wouldn’t offer a testable claim. It’s also not describing a model, which is a simplified representation of a system, or proving a theory, which is a broad explanation supported by many findings over time. The hypothesis sits within theory and provides a concrete, testable guess that researchers can confirm or refute with evidence.
