This skill analyzes A/B test results using statistical rigor to determine whether to ship, extend, or stop an experiment. It enforces disciplined evaluation by verifying sample sizes, checking guardrail metrics, and calculating confidence intervals.

29 13Apache-2.0Updated 2026-07-08

Overview

Designed to prevent premature test conclusions and common statistical fallacies, the A/B test analysis skill provides a clear step-by-step workflow for assessing experiment outcomes. It guides users through validating setup parameters like sample ratio mismatches and test durations, computing core metrics such as relative lift and p-values, evaluating guardrail degradation, and applying a robust decision matrix.

Capabilities

  • Statistical significance calculation
  • Sample Ratio Mismatch (SRM) detection
  • Guardrail metric assessment
  • Decision matrix execution for ship/extend/stop recommendations

Best for

Evaluating completed A/B test conversion data to decide whether to roll out a variant, Assessing statistical and practical significance against predefined Minimum Detectable Effect thresholds, Checking guardrail metrics to ensure primary wins do not negatively impact other critical business metrics
