For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it . Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories . Even though the words "hypothesis" and "theory" are often used synonymously, a scientific hypothesis is not the same as a scientific theory . A working hypothesis is a provisionally accepted hypothesis proposed for further research . </P> <P> A different meaning of the term hypothesis is used in formal logic, to denote the antecedent of a proposition; thus in the proposition "If P, then Q", P denotes the hypothesis (or antecedent); Q can be called a consequent . P is the assumption in a (possibly counterfactual) What If question . </P>
