Null Hypothesis Definition

The null hypothesis is typically abbreviated as H 0 and the alternative hypothesis as H 1.

. The complement of the null hypothesis is called the alternative hypothesis. Thus the null hypothesis is true if the observed data in the sample do not differ from what would be expected on the basis of chance alone. We either reject them or we fail to reject them.

Hence failing to reject the null hypothesis does not mean that we have shown. A null hypothesis is a hypothesis that is never acceptable. The purpose of the null hypothesis is to provide the researcher or an investigator with the relational statement that is directly tested in any research study.

The analysis plan describes how to use sample data to accept or reject the null hypothesis. Formulate an Analysis Plan.
