What problem does it solve?
Helps teams plan, design, and analyze A/B tests and experiments so results are statistically valid, interpretable, and actionable rather than anecdotal or misleading.
Core Features & Use Cases
- Hypothesis Framework & Templates: Provides a clear hypothesis structure and ready-to-use templates for planning and documenting experiments.
- Sample Size & Duration Guidance: Includes reference tables, calculators, and rules of thumb to determine required sample sizes and sensible test durations.
- Design, Implementation & Analysis Checklists: Covers variant design, traffic allocation strategies, client/server implementation considerations, pre-launch QA, tracking verification, analysis checklists, and result interpretation.
- Real-world Example: Use this to plan a pricing page test by defining the hypothesis, calculating sample size for the primary metric (plan selection rate), implementing variants, and following the analysis checklist to decide whether to implement a winner.
Quick Start
Plan an A/B test by providing baseline conversion rate, daily traffic, the minimum detectable effect you care about, the variant change and rationale, and the primary metric to measure.
