SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps users design, plan, and execute statistically valid A/B tests to compare two approaches and measure impact, enabling data-driven product decisions.

Core Features & Use Cases

  • Hypothesis-driven test design: build clear hypotheses, select the appropriate test type (A/B, A/B/n, MVT, or split URL), and determine a plan that isolates changes.
  • Sample size, metrics, and governance: calculate required sample sizes, define primary/secondary/guardrail metrics, and set guardrails to protect business outcomes.
  • End-to-end guidance and templates: provide test templates, runbooks, and best practices for planning, running, and analyzing experiments across product pages, pricing, onboarding, and features.

Quick Start

Create a test plan by formulating a clear hypothesis, selecting a test type, and documenting metrics and sample size using the provided templates.

FAQPage Schema
How do I calculate the required sample size for an A/B test?

To calculate the required sample size for an A/B test, you need to define your primary metrics, expected effect size, and statistical significance thresholds. This skill provides templates to compute sample sizes and plan tests that isolate changes for product features, pricing pages, and onboarding flows.

What is the difference between A/B, A/B/n, MVT, and split URL testing?

A/B and A/B/n tests compare two or more distinct variants, MVT evaluates multiple variable combinations simultaneously, and split URL tests route traffic to entirely different pages. This skill helps you select the appropriate test type based on your hypothesis and product experimentation requirements.

How do I set up primary, secondary, and guardrail metrics for experimentation?

To set up metrics for experimentation, define primary metrics to measure the main goal, secondary metrics for additional insights, and guardrail metrics to protect business outcomes. This skill provides templates to structure these metrics and ensure statistically valid product experiments.

Can I use this skill to design A/B tests for pricing pages and onboarding flows?

Yes, you can use this skill to design A/B tests for pricing pages and onboarding flows. It supports formulating clear hypotheses, selecting test types, and documenting metrics and sample sizes to compare variants and decide which performs better for data-driven product decisions.

What is the best way to construct a hypothesis for an A/B test?

The best way to construct an A/B test hypothesis is to clearly define the expected change, the target metric, and the predicted outcome. This skill provides end-to-end guidance and runbooks to build hypothesis-driven test designs that isolate changes and measure impact effectively.
