Why is replication important in the scientific method?

A scientific method is a sequence or collection of processes that are considered characteristic of scientific investigation and the acquisition of new scientific knowledge based upon physical evidence. Make Observations -> Think of interesting questions -> Formulate Hypotheses -> Develop Testable predictions -> Gather Data to test predictions בשלב זה יש או ללכת ל- Refine, Alter, Expand or Reject Hypotheses ואז לחזור ל-Develop Testable predictions או שממשיכים ל-Develop General Theories ואז הכל חוזר חלילה
