ab-test-analysis skillA
ab-test-analysis is agent-read markdown (skill) from akillness/jeo-skills: Analyze A/B test results with statistical significance, sample size validation, confidence intervals, and ship/extend/stop recommendations. Use when evaluating experiment results, checking if a test reached significance, interpreting split test data, or deciding whether to ship a variant..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
## A/B Test Analysis
Evaluate A/B test results with statistical rigor and translate findings into clear product decisions.
### Context
You are analyzing A/B test results for **$ARGUMENTS**.
If the user provides data files (CSV, Excel, or analytics exports), read and analyze them directly. Generate Python scripts for statistical calculations when needed.
### Instructions
1. **Understand the experiment**:
- What was the hypothesis?
- What was changed (the variant)?
- What is the primary metric? Any guardrail metrics?
- How long did the test run?
- What is the traffic split?
2. **Validate the test setup**:
- **Sample size**: Is the sample large enough for the expected effect size?
- Use the formula: n = (Z²α/2 × 2 × p × (1-p)) / MDE²
- Flag if the test is underpowered (<80% power)
- **Duration**: Did the test run for at least 1-2 full business cycles?
- **Randomization**: Any evidence of sample ratio mismatch (SRM)?
- **Novelty/primacy effects**: Was there enough time to wash out initial behavior changes?
3. **Calculate statistical significance**:
- **Conversion rate** for control and variant

How to install
mdr add akillness/jeo-skills/ab-test-analysis@git:20260919.9f2a908mdr add akillness/jeo-skills/ab-test-analysis@sha256:9956966671d6d19dPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
