When testing for the equality of 3 population means, we should use the F test statistic. The F distribution is the appropriate distribution to use when comparing the variances of two or more populations. This test compares the ratio of the variance between groups to the variance within groups, and is commonly used in ANOVA (analysis of variance) tests. The F test statistic can be used to determine if the means of three or more groups are significantly different from each other.
