The null hypothesis is the hypothesis that there is no difference between two groups. For example, if you are testing whether or not there is a difference between the means of two groups, the null hypothesis would be that there is no difference between the means of the two groups.

How do you determine the null hypothesis? There are many ways to determine the null hypothesis. One common method is to use a statistical test, such as a t-test or ANOVA, to compare the means of two groups. If the null hypothesis is true, then the means of the two groups should be equal. If the null hypothesis is false, then the means of the two groups will be different. Why does null mean? Null means that there is no value for the financial ratio in question.
