The scientific method is an empirical method of acquiring knowledge that has characterized the development of science. The method generally consists of the following steps.
The first step is to formulate a question, based on observations, and working from existing knowledge.
A hypothesis is a proposed explanation of the observations made in the previous step.
Based on the hypothesis that has been formed, predict the results of some test that might prove or disprove the hypothesis.
Perform one or more experiments whose previously unknown results have been predicted based on the hypothesis that has been formed. It is important to carefully record as much data as possible about the experiment(s) conducted, to aid in peer review and attempts to replicate the results.
Analyze the results of the experiment(s) performed, and compare actual results to those that had been predicted based on the hypothesis. This analysis might typically have one of the following outcomes:
aka: attempts to replicate
Others should be able to replicate an experiment and achieve the same, or similar results. If the results cannot be replicated, then this would imply some error(s) made in the original experiment.
Qualified experts not involved in the process up to now should be allowed to review the experiment and its results, including data collected, to validate the soundnesss of the approach taken and the analysis performed.
The conclusions reached, along with information describing the entire process, can then be published to a wider community, to be referenced and consulted as the basis for further scientific study, and/or application to engineering development.
