WebThis One-way ANOVA Test Calculator helps you to quickly and easily produce a one-way analysis of variance (ANOVA) table that includes all relevant information from the observation data set including sums of squares, mean squares, degrees of freedom, F- and P-values. To use the One-way ANOVA Calculator, input the observation data, … WebANOVA provides p-values and differences between means. Then, you can use post-hoc analysis (Tukey’s, etc), which are commonly used in conjunction with ANOVA to see how the groups compare, to obtain CIs for the differences between the means. Typically, I find CIs provide much more information than a simple point estimate of the effect.
