Wilcoxon Signed Rank Test Calculator
Wilcoxon Signed Rank Test: a planned Super Calculator tool. Covers paired observations and alpha. Stub page while the tool and its worked example are prepared.
Wilcoxon Signed Rank Test Calculator is a planned calculator in the mathematics section of Super Calculator, covering statistics and probability.
What this calculator will compute
Inputs: paired observations, alpha, tail selection and zero-difference handling.
Outputs: W statistic, z, p value, signed rank table and matched-pairs rank biserial correlation.
Formula, recorded as scope and not yet verified against a primary source: Rank the absolute nonzero differences, sum the ranks by sign, and take W = min(W+, W-). Exact null distribution for small n; otherwise z = (W - n(n+1)/4) / sqrt(n(n+1)(2n+1)/24) with tie and zero corrections.
