Kruskal Wallis Test Calculator
Kruskal Wallis Test: a planned Super Calculator tool. Covers three or more independent data groups. Stub page while the tool and its worked example are.
Kruskal Wallis Test Calculator is a planned calculator in the mathematics section of Super Calculator, covering statistics and probability.
What this calculator will compute
Inputs: three or more independent data groups and alpha.
Outputs: H statistic, df, p value, corrected H for ties, mean ranks and epsilon squared effect size.
Formula, recorded as scope and not yet verified against a primary source: H = (12 / (N(N+1))) * sum(R_i^2 / n_i) - 3(N+1), compared to chi-square with k-1 degrees of freedom. Ties require dividing H by 1 - sum(t^3 - t)/(N^3 - N).
