One-way ANOVA calculator includes the Tukey HSD test. Calculates the effect size and checks the assumptions: normality, equality of variances, test power.

This is analogous to the classical one-way ANOVA design that is used to analyze means of normal outcomes. In the case of only two groups, this procedure produces power and sample size estimates that match those from the two independent-group Poisson means procedure. The methods used in...

We investigated coverage probability for confidence intervals (CIs) for the Root Mean Square Standardized Effect Size (RMSSE, denoted by ) and a robust version (RMSSEdenoted by ), which we proposed in this study, in a balanced, one-way, fixed-effects, between-subjects ANOVA desi...

Prism 9. For two-group comparison statistical significance was determined using a two-tailed unpairedt-test. Multiple group comparison was analyzed by one-way ANOVA followed by Tukey-Kramer multiple comparison posthoc analysis. A difference with ap-value below 0.05 was considered statistically ...
The statistical analysis was performed using GraphPad Prism software (GraphPad Software, Inc.; San Diego, CA, USA; 2017). Normal distribution analysis was performed using the Shapiro–Wilk test to distinguish parametric and nonparametric data. One-way ANOVA and Tukey’s post-test were used to ana...
