What phrase best describes the scientific method?

The phrase that best describes the scientific method is the formulation of a hypothesis and adjustment based on data. This process begins with a researcher observing a phenomenon and proposing a hypothesis, which is a testable prediction about the relationship between variables. The scientific method emphasizes that hypotheses must be tested through experimentation and observation.

As data is collected, it is analyzed to determine whether the evidence supports or refutes the hypothesis. Importantly, this step often leads to adjustments and refinements of the hypothesis based on the findings. This cyclical nature of hypothesis testing and revision is foundational to scientific inquiry, allowing for continuous improvement and deeper understanding of the subject matter. It conveys that science is not just about proving an idea, but also about evolving it through evidence-based adjustments.

In contrast, simply collecting data without forming or testing a hypothesis does not align with the scientific method, as it lacks the necessary framework for inquiry. Data analysis alone also misses the crucial aspect of hypothesis testing. Conclusive testing without revisions undermines the iterative nature of scientific discovery, where ongoing testing and refinement are vital. Hence, the process of starting with a hypothesis and adjusting it based on collected data encapsulates the heart of the scientific method.
