Quizplus · Accepted Answer

A hypothesis is a testable prediction based on theoretical or observed evidence, and Tom's statement meets this description. A theory is a well-established set of explanations for observed phenomena, which goes beyond a single hypothesis. Correlation simply states that there is a relationship between two variables, without any explanation or prediction for why that relationship exists. A statement could refer to any piece of information, without necessarily being a hypothesis or theory.
