Unlike Analysis of Variance (ANOVA), which compares one group mean to another group mean, ANOM compares each group mean to the overall mean. The calculations in ANOM are simple and direct. ANOM also avoids many of the ambiguities inherent in the multiple comparisons used in ANOVA, and avoids a common misinterpretation about overlapping confidence intervals.
In this training, we illustrate the mechanics of calculating ANOM and provide context for when you should or should not use it.Note: This training is an exclusive benefit to members of the Statistically Speaking Membership Program and part of the Stat’s Amore Trainings Series. Each Stat’s Amore Training is approximately 90 minutes long.
