An experiment helps scientists to control and change the conditions under which events occur. Scientists repeat experiments, sometimes many times, in order to be sure that the results were not affected by any factors.
During an experiment, scientists make predictions and collect . Once an experiment has been and data collected and , scientists a hypothesis that explains all the facts observed in an experiment. In developing a hypothesis, scientists employ methods of induction to generalize from the experiment’s results to predict future outcomes, and deduction to infer new facts from experimental .
