Frequently Asked Questions

What does alternative hypothesis stand for?

The alternative hypothesis is the hypothesis you are actually testing - if the evidence is consistent with the alternative hypothesis you will accept it. The null hypothesis is what you believe, by default, to be the case if the alternative hypothesis is not true.

Why do we need alternative hypothesis?

They are useful if they have explanatory power. The purpose and importance of the null hypothesis and alternative hypothesis are that they provide an approximate description of the phenomena . The purpose is to provide the researcher or an investigator with a relational statement that is directly tested in a research study.

Do you test the null or alternative hypothesis?

There are two outcomes of a statistical test, i.e. first, a null hypothesis is rejected and alternative hypothesis is accepted, second, null hypothesis is accepted, on the basis of the evidence. In simple terms, a null hypothesis is just opposite of alternative hypothesis.
