Which of the following describes correctly the scientific method?

Question

BlackTom AI · Accepted Answer

Form a hypothesis is the first actionable scientific step: you propose a tentative, testable explanation based on observations. Next you design and perform tests (experiments) that will generate data relevant to that hypothesis. After running the tests you collect the empirical data produced and finally interpret those data to accept, reject, or revise the hypothesis.

1) Relevant knowledge points and concepts
- Hypothesis: a falsifiable, testable proposition derived from observation.
- Experiment/test: a controlled procedure to evaluate the hypothesis.
- Data collection: recording the measurements/observations produced by the test.
- Interpretation: analyzing results to draw conclusions and refine hypotheses or develop theories.

2) Complete reasoning process step by step
Step 1: Form a hypothesis (propose an explanatory statement).  
Step 2: Test the hypothesis (design and carry out experiments or observations).  
Step 3: Collect data produced by those tests (measurements, observations).  
Step 4: Interpret data to determine whether the hypothesis is supported or must be revised.

3) Intermediate logical steps shown
- Observation → hypothesis formulation.
- Hypothesis → experimental design.
- Experiment → measurable outcomes (data).
- Data analysis → conclusion (support, modify, or reject hypothesis).

4) Why the correct answer is correct
The correct option precisely follows the logical flow: hypothesis leads to testing; testing produces data which must be collected; and only after data are assembled can they be interpreted. This order preserves the requirement that experiments be hypothesis-driven and that interpretation rely on empirical evidence.

5) Why the other options are incorrect
- Option 1 (Collect data → Form a hypothesis → Test the data → Interpret data): Puts data collection before hypothesis formulation and uses the phrase “test the data” (nonsensical); experiments should be guided by hypotheses.  
- Option 2 (Test the hypothesis → Collect data → Interpret data → Form a hypothesis): Tests before forming a hypothesis is backwards; interpretation before forming the hypothesis is illogical.  
- Option 4 (Form a theory → Collect data → Form a hypothesis → Test hypothesis): Forming a theory precedes hypothesis and testing, which reverses the development sequence (theory comes after repeated confirmation).

6) Conclusion
Therefore the correct sequence is "Form a hypothesis --> Test the hypothesis --> Collect data --> Interpret data," which matches the provided answer.
