Why might the order of steps in the scientific method vary?

• The scientific method is only applicable to biology.
• Because different experiments may require different approaches

• All scientists agree on a universal order of steps.
• The steps must always be followed in a strict order.

According to the scientific method, what should you do after analyzing data and drawing conclusions?

• Decide if the hypothesis is supported or not supported

  
  

• Store the data in a file.
• Repeat the experiment without changes.
• Ignore the results.

A scientist tests a hypothesis with a single experiment, analyzes the data, and finds that the hypothesis is supported. What is the next logical step?
