Analysis of variances (ANOVA) is the appropriate statistical test that allows for multiple comparisons of means of three, four, five, or more different groups. It assesses whether there are differences between the means of the groups while controlling for the overall alpha level to minimize type I error. ANOVA has different variations, such as one-way ANOVA for a single dependent variable and one independent variable, and factorial ANOVA for multiple independent variables.
