Compare two independent samples using the nonparametric Mann-Whitney U rank-sum test. Compute U₁ and U₂ statistics, z-approximation with optional continuity correction, exact p-values, effect size r, APA 7th Edition reports, and step-by-step mathematical derivations. When non-parametric test concepts get overwhelming and you decide to hire someone to take your statistics course for you, our platform provides complete academic assistance.
