What are Null and Alternate Hypothesis?


  • Null hypothesis(H0): In statistics, the null hypothesis is a general given statement or default position that there is no relationship between two measured cases or no relationship among groups.
  • In other words, it is a basic assumption or made based on the problem knowledge.
    Example: A company production is = 50 unit/per day etc.


  • Alternative hypothesis(H1): The alternative hypothesis is the hypothesis used in hypothesis testing that is contrary to the null hypothesis.
    Example : A company production is not equal to 50 unit/per day etc.
