Which statement describes the purpose of a hypothesis in experimentation?

• A. It guides experiments and is testable
• B. It is proven, so experiments are unnecessary
• C. It guarantees a positive outcome
• D. It replaces data collection

Answer: (B)

A hypothesis in experimentation is a testable, tentative explanation that provides a specific prediction to evaluate. It guides how you design the study, including what variables to measure and what results would support or challenge the idea. Because a hypothesis is testable, experiments are built to gather evidence that can confirm or refute it, rather than proving it once and for all from the start. A good hypothesis is falsifiable, meaning there are clear observations that could show it to be false. It does not promise a positive outcome, and it does not replace the need to collect data—the data are what determine whether the hypothesis holds. Describing a hypothesis as something proven and making experiments unnecessary misses the essential purpose of testing ideas, which is why the testable, guiding description is the best fit.
