This initial statement is called the Null Hypothesis and is denoted by Ho. An alternative or alternate hypothesis (denoted Ha), is then stated which will be the opposite of the Null Hypothesis.

A null hypothesis is often written as H0 and paired with an alternative hypothesis (H1) that predicts a relationship or effect.

The alternative hypothesis (called H1) is a statement that is the opposite of the null hypothesis and usually follows the format that “there is a difference between these two numbers” or “there is a ...

The null hypothesis is always that there is no relationship, no effect, or no difference. If you've taken statistics, you know that traditional statistics work by testing the null hypothesis.

The “Null Hypothesis” Hypothesis testing begins with a statement, known as the null hypothesis. The statement is typically one which says that there is “nothing” special going on, and that “no” ...

This paper considers testing problems where several of the standard regularity conditions fail to hold. We consider the case where (i) parameter vectors in the null hypothesis may lie on the boundary ...

The null hypothesis offers a unique approach to identifying weaknesses in business models, fostering innovation.

The distribution of p values under the null hypothesis is uniform. However, under the alternative hypothesis the distribution of the p values is skewed. The expected p value (EPV) has been proposed by ...
