How is a single factor ANOVA used to test the null hypothesis?Ī single factor or one-way ANOVA is used to test the null hypothesis that the means of several populations are all equal. A rough interpretation would be that the p-value reflects how much confidence you can have that the null hypothesis is a reasonable model. For one-way ANOVA, the null hypothesis is that the means for each level of your factor are the same. The p-value has meaning only with respect to the null hypothesis of the ANOVA analysis. In the 2-Way ANOVA dialog (see screenshot ) you can enter the following parameters: Data range, with or without labels: A rectangular range of cells that may or may not contain labels. Like all hypothesis tests, one-way ANOVA uses sample data to make inferences about the properties of an entire population.
