What is the purpose of forming a hypothesis in the scientific method?

• A. A guess without any supporting observation.
• B. A testable statement predicting an outcome based on prior observation.
• C. A summary of all experimental results.
• D. A final conclusion after experiments.

Answer: (B)

Forming a hypothesis means creating a testable statement that predicts what will happen under certain conditions, based on prior observations. This guides the experiment by specifying what will be measured and what results would support or refute the idea, making the investigation focused and interpretable. A hypothesis should be testable and falsifiable, so data can be collected to show whether it holds up. It’s more than a guess; it links what’s already known to a possible outcome that can be evaluated with evidence. It isn’t a summary of results or a final conclusion—that comes after testing. So the best description is a testable statement predicting an outcome based on prior observation.
