WebJan 27, 2024 · Note: The One-Way ANOVA is considered an omnibus (Latin for “all”) test because the F test indicates whether the model is significant overall—i.e., whether or not there are any significant differences in the means between any of the groups. (Stated another way, this says that at least one of the means is different from the others.)
