11. Hypotheses are explanations of observed facts

Question

BlackTom AI · Accepted Answer

A hypothesis is a tentative, testable explanation for an observed phenomenon or set of facts, so the correct answer is TRUE.

1. Relevant knowledge points and concepts
- Hypothesis: a proposed explanation based on limited evidence that leads to testable predictions.  
- Scientific method: observation → hypothesis → prediction → experiment/observation → accept/revise/reject.  
- Testability and falsifiability: a scientific hypothesis must make predictions that could, in principle, be shown false.

2. Step-by-step reasoning
- Start with observed facts: scientists notice a pattern, anomaly, or measurement.  
- Formulate a hypothesis that accounts for those facts. This hypothesis provides an explanatory mechanism (why the facts occur).  
- Derive specific, testable predictions from the hypothesis.  
- Perform experiments or further observations to check whether the predictions hold. If predictions match observations, the hypothesis is supported (but not absolutely proven); if not, it is rejected or revised.

3. Intermediate steps (illustrative example)
- Observation: plants near a window grow faster.  
- Hypothesis: increased light exposure causes faster growth.  
- Prediction: Moving plants to brighter light will increase their growth rate.  
- Test: Measure growth in controlled light conditions; compare results to prediction.

4. Why the correct answer is correct
- A hypothesis’s primary role is to explain observed facts in a way that leads to testable predictions. That definition directly matches the statement "Hypotheses are explanations of observed facts," making TRUE correct.

5. Why the other options are incorrect
- "FALSE" contradicts the established definition of hypothesis in science.  
- The options labeled "No answer text provided." are non-answers and do not address the statement; they cannot be correct.

6. Conclusion
- Given the definition and role of hypotheses in the scientific method, the statement is TRUE, which matches the provided correct answer.
