Meanings
nounnull hypothesis (plural null hypotheses)
plural null hypotheses
- mathematicsA 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.
A two proportion z-test allows for a comparison of two proportions, with the null hypothesis being that they are the same.
