Which statement best defines a hypothesis?

• A. A Hypothesis
• B. A Theory
• C. An Opinion
• D. A Comment

Answer: (A)

A hypothesis is a testable statement about a potential relationship between variables that researchers can examine with data. It makes a clear, falsifiable prediction—often specifying the direction of the relationship and the conditions under which it should hold—so that evidence can either support or refute it through observation or experiment. In practice, hypotheses guide what data to collect and how to analyze it, turning ideas into testable claims. This differs from a theory, which is a broad, well-supported explanation that ties together many findings and phenomena. It also differs from an opinion, which is a personal belief not necessarily grounded in evidence, and from a mere comment, which is just a remark without a testable claim. A hypothesis sits at the point of testable prediction, ready to be explored with data.
