The hypothesis actually to be tested is usually given the symbol H0, and is. commonly referred to as the null hypothesis. As is explained more below, the null hypothesis is. assumed to be true unless there is strong evidence to the contrary â similar to how a person is. assumed to be innocent until proven guilty.
Null hypothesis. Definition. noun. (1) An assumption or proposition where an observed difference between two samples of a statistical population is purely accidental and not due to systematic causes. (2) The hypothesis to be investigated through statistical hypothesis testing so that when refuted indicates that the alternative hypothesis is true. Supplement. A null hypothesis is a hypothesis that is valid or presumed true until invalidated by a statistical test. Thus, one cannot say that a null hypothesis is ââacceptedââ rather a null hypothesis ââcannot be rejectedââ as it remains to be true based on the statistical evidence supporting it.
