• To provide extra data in case you lose some of it
• To satisfy the requirement that experiments have a minimum of 10 data points

In what order are the steps of the scientific method usually completed? 

• Form a Hypothesis, Define the problem, Perform Experiments, Organize and Analyze Data, Draw Conclusions, Communicate Results.
• Define the problem, Form a Hypothesis, Organize and Analyze Data, Perform Experiments, Draw Conclusions, Communicate Results.
