   16 cze 2022 · Understanding the Null Hypothesis for ANOVA Models. by Zach BobbittJune 16, 2022. A one-way ANOVA is used to determine if there is a statistically significant difference between the mean of three or more independent groups. A one-way ANOVA uses the following null and alternative hypotheses: H0:μ1= μ2= μ3= … = μk(all of the group means are equal)

   What it means is that, if the null hypothesis is true, then the sampling distribution of the \(F\) ratio has a mean of 1, [3] and so we need to see \(F\)-values larger than 1 in order to safely reject the null.
