Verified step by step guidance

1. Understand that a hypothesis in the scientific method is a proposed explanation or prediction that can be tested through experiments or observations.
2. Recognize that a good hypothesis must be testable, meaning it can be supported or refuted by empirical evidence.
3. Know that a crucial feature of a good hypothesis is falsifiability, which means it can potentially be proven wrong by data or experiments.
4. Avoid hypotheses based on personal beliefs or opinions, as these cannot be objectively tested or measured.
5. Avoid hypotheses stated as absolute facts or too broad to be tested, since they do not allow for meaningful scientific evaluation.
