Problem:OPTIONS:
- conclusion
- materials
- suggestions
- hypothesis

Answer the following question given this paragraph: The scientist must next form a conclusion. The scientist must study all of the data. What statement best explains the data? Did the experiment prove the hypothesis? Sometimes an experiment shows that a hypothesis is correct. Other times the data disproves the hypothesis. Sometimes it's not possible to tell. If there is no conclusion, the scientist may test the hypothesis again. This time he will use some different experiments. No matter what the experiment shows the scientist has learned something. Even a disproved hypothesis can lead to new questions. Q: If no conclusion is reached after an experiment, the scientist may retest what? A:
****
A:
hypothesis
