Why is the scientific method considered a circular process?

The scientific method is considered a circular process because it emphasizes the iterative nature of research. Each step of the scientific method leads to the next, but the outcomes also frequently prompt revisiting earlier steps. For example, a researcher may formulate a hypothesis after reviewing existing literature, conduct an experiment to test this hypothesis, analyze the results, and then interpret the findings. If the results do not support the hypothesis, the researcher may revise the hypothesis or develop new questions that lead back to additional experiments.

This cyclical nature allows scientists to refine their concepts, improve their experimental designs, and ultimately build deeper understanding over time. Thus, while there is often a structured progression, the reality of research is that it frequently loops back on itself, allowing for continual refinement of ideas and conclusions. This is why the correct answer highlights the necessity of taking steps in a specific order rather than disregarding the order entirely, which could lead to confusion or unreliable results.
