Answer:
The scientific method <em>involves testing observations to derive a working hypothesis.</em>
Explanation:
The scientific method is a research method used to produce knowledge. It consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility (the capability of reproducing the experiment in any other place by any researcher) and refutability (susceptibility to be refused).
There are different steps to follow in a scientific method:
- Definition and problem statement. The question for which there is not an answer yet.
- Data collection and analysis. This step involves testing the observations.
- Verification of hypothesis. This step involves the deriving of the working hypothesis.
- Conclusions and Discussion.
