Null Hypothesis Definition
noun
A hypothesis that is assumed to be true for purposes of statistical testing against an alternative hypothesis. The null hypothesis is usually that there is no treatment effect or no difference between groups.
American Heritage
(statistics) A hypothesis set up to be nullified or refuted in order to support an alternative hypothesis. When used, the null hypothesis is presumed true until statistical evidence in the form of a hypothesis test indicates otherwise. Therefore, the null and the alternative hypothesis must be mutually exclusive and exhaustive. The use of the null hypothesis is controversial.
