英文释义

名词 n.
  1. 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.
    — A two proportion z-test allows for a comparison of two proportions, with the null hypothesis being that they are the same.
