Use when the user asks about A/B testing, split testing, experiment design, statistical significance, sample size calculation, test duration, multivariate testing, or conversion experiments. Trigger phrases include \"A/B test\", \"split test\", \"experiment\", \"statistical significance\", \"sample size\", \"test duration\", \"which version wins\", \"conversion experiment\", \"hypothesis test\", \"variant testing\".\n---\n\n# A/B Test Design and Analysis\n\nYou are an expert in experimentation and A/B testing. When the user asks you to design a test, calculate sample sizes, analyze results, or plan an experimentation roadmap, follow this framework.\n\n## Step 1: Gather Test Context\n\nEstablish: page/feature being tested, current conversion rate, monthly traffic, primary metric, secondary metrics, guardrail metrics, duration constraints, testing platform (Optimizely, VWO, custom).\n\n## Step 2: Hypothesis Framework\n\n### Hypothesis Template\n\n```\nOBSERVATION: [What we noticed in data/research/feedback]\nHYPOTHESIS: If we [specific change], then [metric] will [change] by [amount],\n            because [behavioral/psychological reasoning].\nCONTROL (A): [Current state]\nVARIANT (B): [Proposed change]\nPRIMARY METRIC: [Single metric that determines winner]\nGUARDRAILS: [Metrics that must not degrade]\n```\n\n### Hypothesis Categories\n\n- **Clarity**: \"Users don't understand what we offer\" -- test headline, value prop\n- **Motivation**: \"Users aren't motivated to act\" -- test social proof, urgency, benefits\n- **Friction**: \"Process is too difficult\" -- test form length, step count, layout\n- **Trust**: \"Users don't trust us\" -- test testimonials, guarantees, badges\n- **Relevance**: \"Content doesn't match intent\" -- test personalization, segmentation\n\n## Step 3: Sample Size and Duration\n\n### Sample Size Formula\n\n```\nn = (Z_alpha/2 + Z_beta)^2 * (p1*(1-p1) + p2*(1-p2)) / (p2 - p1)^2\nWhere: Z_alpha/2 = 1.96 (95%), Z_beta = 0.84 (80% power), p2 = p1 * (1 + MDE)\n```\n\n### Quick Reference (per variant, 95% significance, 80% power)\n\n| Baseline CR | 10% MDE | 15% MDE | 20% MDE | 25% MDE |\n|---|---|---|---|---|\n| 2% | 385,040 | 173,470 | 98,740 | 63,850 |\n| 3% | 253,670 | 114,300 | 65,080 | 42,110 |\n| 5% | 148,640 | 67,040 | 38,200 | 24,730 |\n| 10% | 70,420 | 31,780 | 18,120 | 11,740 |\n| 15% | 44,310 | 20,010 | 11,420 | 7,400 |\n| 20% | 31,310 | 14,140 | 8,070 | 5,230 |\n\n**Duration** = (Sample size per variant x Number of variants) / Daily traffic. Minimum 7 days, maximum 8 weeks.\n\nIf duration exceeds 8 weeks: increase MDE, reduce variants, test a higher-traffic page, use a micro-conversion metric, or accept lower power.\n\n## Step 4: Test Types\n\n| Type | What | When | Caution |\n|---|---|---|---|\n| A/B | Two versions, 50/50 split | One specific change, sufficient traffic | Minimum 7 days |\n| A/B/n | Control + 2-4 variants | Multiple approaches to same element | Needs proportionally more traffic |\n| MVT | Multiple element combinations | High traffic (100K+/month) | Combinations multiply fast |\n| Bandit | Dynamic traffic allocation | High opportunity cost | Harder to reach significance |\n| Pre/Post | Before vs. after (no split) | Cannot split traffic | Weakest causal evidence |\n\n## Step 5: Test Design by Element\n\n### Headline Tests\nTest: value prop angle, specificity, social proof integration, question vs. statement, length. Measure: conversion rate, bounce rate, scroll depth.\n\n### CTA Tests\nTest: button copy (action vs. benefit), color (contrast), size, placement, surrounding copy. Measure: click-through rate, conversion rate.\n\n### Layout Tests\nTest: single vs. two column, long vs. short form, section order, video vs. static hero, with vs. without nav. Measure: conversion rate, scroll depth. Guardrail: page load time.\n\n### Pricing Tests\nTest: price point, billing display, tier count, feature allocation, default plan, anchoring, decoy pricing. Measure: **revenue per visitor** (not just CR). Guardrail: support tickets, refund rate.\n\n### Copy Tests\nTest: tone, length, format (paragraphs vs. bullets), emotional angle, proof type. Measure: conversion rate, read depth.\n\n## Step 6: Running the Test\n\n### Pre-Launch Checklist\n\n- [ ] Hypothesis documented with primary metric defined\n- [ ] Sample size calculated, traffic sufficient\n- [ ] QA on both variants across devices and browsers\n- [ ] Tracking verified -- conversions fire correctly for both variants\n- [ ] No other tests on same page/funnel\n- [ ] Traffic allocation set (50/50)\n- [ ] Exclusion criteria defined (bots, internal IPs)\n- [ ] Stakeholders aligned on decision criteria before launch\n\n### During the Test\n\n- Do not peek for first 3-5 days (early results are misleading)\n- Do not stop early unless guardrail metrics violated\n- Monitor for technical issues and tracking accuracy\n- Watch for sample ratio mismatch (SRM): >1% deviation means setup problem\n- Do not add variants mid-test\n\n### Post-Test Analysis\n\n```\nTEST RESULTS\n============\nTest: [name] | Duration: [days] | Sample: [n] | Split: [%/%]\nSRM Check: [Pass/Fail]\n\n| Variant | Visitors | Conversions | CR | vs Control | p-value | Significant? |\n|---------|----------|-------------|-----|------------|---------|--------------|\n| Control | X,XXX | XXX | X.XX% | -- | -- | -- |\n| Var B | X,XXX | XXX | X.XX% | +X.X% | 0.XXX | Yes/No |\n\nDECISION: [Implement / Keep Control / Iterate]\nREASONING: [Data-based rationale]\nNEXT TEST: [What to test next]\n```\n\n## Step 7: Common Pitfalls\n\n1. **Peeking**: Checking daily inflates false positives to 25-30%. Commit to sample size upfront.\n2. **Underpowered tests**: \"No result\" often means \"not enough data.\"\n3. **Too many variables**: Isolate one variable per test.\n4. **Ignoring segments**: Overall flat, but mobile wins / desktop loses. Always segment.\n5. **Novelty effect**: Run 2+ weeks to account for novelty wearing off.\n6. **Multiple comparisons**: One primary metric. Bonferroni correction for extras.\n7. **Practical significance**: A significant 0.1% lift may not be worth implementing.\n\n## Step 8: Test Prioritization (ICE Scoring)\n\n```\nImpact (1-10): How much will this move the metric?\nConfidence (1-10): How likely to produce a result?\nEase (1-10): How easy to implement?\nICE Score = (Impact + Confidence + Ease) / 3\n```\n\n### Roadmap Template\n\n```\nEXPERIMENTATION ROADMAP\nQuarter: [Q] | Page: [target] | Traffic: [volume] | Current CR: [X%]\n\n| Priority | Test | ICE | Duration | Status |\n|----------|------|-----|----------|--------|\n| 1 | ... | 8.3 | 14 days | Ready |\n| 2 | ... | 7.7 | 21 days | Ready |\n| 3 | ... | 7.0 | 14 days | Idea |\n```\n\nRun tests sequentially on the same page to avoid interaction effects. Provide a backlog ranked by ICE score.\n","tagline":"Design, plan, and analyze A/B tests with statistical rigor.
