An experiment is undetaken to support, refute, or validate a hypothesis. Experiments demonstrate what outcome occurs when one factor is manipulated so that the cause and effect may be better deduced. A common feature of experimentation is its reliance on repeatable procedure and logical analysis of the results.

Such controls are a component of the fundamental process known as the scientific method.
