A/B Test: Binary Design, Data Checks and Decision
Plan an independent binary-outcome experiment, check assignment counts and analyze the actual 2×2 table with effect intervals and explicit decision criteria.
Statistical Inference: Design, Estimation and Reporting
Plan a statistical comparison, match methods to the sampling design, report effects and uncertainty, and preserve assumptions and analysis decisions.
Landing Page Conversion Measurement and Experiments
Build a credible offer, verify the full conversion path and plan a defined binary experiment using explicit denominators, sample assumptions and stopping rules.

Plan approximate samples for an equal-allocation, two-sided comparison of independent binary conversion rates with explicit effect, significance and power.
Calculators
Compare explicit two-sided power models for one known-variance mean, two independent means or independent binary rates with continuous alpha.
Calculators
Test categorical goodness of fit or an independent 2×2 outcome table, with actual p-values, Fisher support and labeled proportion-difference intervals.
Calculators
Compare an unrounded reported p-value with prespecified alpha, without interpreting it as effect size, a confidence interval or hypothesis probability.
Calculators
Calculate percentages in seven modes with visible formulas, strict input validation, signed percentage change, and symmetric percentage difference.
Calculators
Compare two opaque sRGB colors using WCAG text contrast ratios. See precise ratio estimates, unrounded threshold decisions and clear invalid-color feedback.
