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.

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.
