# Statistical Analysis

You have data and a question - it picks the right test

## What this does

You have experimental or survey data and want to compare groups or test an idea, but you are not sure which test applies or whether your data qualifies for it. This walks you through choosing, checking the assumptions, reporting effect sizes, and writing the result up - even if you never name a test yourself.

### Top 3 things it does for you

- Work out which statistical test fits your question
- Check whether your data meets the assumptions
- Compute effect sizes and required sample sizes

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Statistical Analysis

Guided statistical analysis for research data: test selection, assumption checking, effect sizes, power analysis, Bayesian alternatives, and APA-formatted reporting.

Use it whenever you want to compare groups, test a hypothesis, analyze experimental or survey data, check statistical assumptions, compute required sample sizes, or write up results - including when you have no particular test in mind. It covers t-tests, ANOVA, chi-square, correlation, regression, and non-parametric and Bayesian methods.

For low-level model APIs, the pointers are to the statsmodels and pymc skills.

## Questions

### Is Statistical Analysis safe to install?

AIR scanned this exact version of Statistical Analysis and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 81e316bc89f7, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/statistical-analysis.

### How do I install Statistical Analysis?

Open https://airmarket.ai/app/statistical-analysis on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/k-dense-ai/scientific-agent-skills/tree/81e316bc89f7fda176b092d2bceb959204710b0a/skills/statistical-analysis. Install from that link, not the branch.
