This self-contained calculator, with flexibility to vary the number of treatments (columns) to be compared, starts with one-way ANOVA. If ANOVA indicates statistical significance, this calculator automatically performs pairwise post-hoc Tukey HSD, Scheffé, Bonferroni and Holm multiple comparison of all treatments (columns).
One-way ANOVA calculator includes the Tukey HSD test. Calculates the effect size and checks the assumptions: normality, equality of variances, test power.
One-Way ANOVA Calculator, Including Tukey HSD. The one-way, or one-factor, ANOVA test for independent measures is designed to compare the means of three or more independent samples (treatments) simultaneously.
Friedman Test Calculator. The friedman test is the equivalent nonparametric test to the one-way repeated measures ANOVA. The friedman test checks if the difference between the ranks of two or more dependent groups is significant.
