Analysis of variance (ANOVA) is the appropriate analysis when examining the differences in group means among three or more groups. ANOVA allows for the comparison of means between multiple groups to determine if there are statistically significant differences present. This analysis calculates an F-statistic which compares the between-group variability to the within-group variability.
