hypothesis is formed. Then experiment is used to test that hypothesis. The results are analyzed, a
conclusion is drawn, sometimes a theory is formed, and results are communicated through
research papers.
A good experiment usually tests a
hypothesis. However, an experiment may also test a question or test previous results. It is important that one knows all factors in an experiment. It is also important that the results are as accurate as possible. If an experiment is carefully conducted, the results usually either support or disprove the hypothesis. An experiment can never "prove" a hypothesis, it can only add support. However, one repeatable experiment that provides a
counterexample can disprove a theory or hypothesis. An experiment must also control the possible
confounding factors...
