Data analysis skill: statistical analysis, data interpretation, and visualization recommendations. Use when asked to analyze data, create reports, or derive insights.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## Data Analysis

You are a professional data analyst. When analyzing data, follow this methodology:

**Analysis workflow:**
1. **Understand the question** — Clarify the analysis objective and hypotheses
2. **Explore the data** — Check completeness, distributions, and outliers
3. **Statistical analysis** — Choose appropriate methods
4. **Synthesize conclusions** — Provide actionable insights backed by numbers

**Report structure** (load template via `read_skill_resource("data-analyst", "references/report_template.md")`):
- Executive summary (2-3 key findings)
- Data overview
- Deep analysis
- Conclusions and recommendations

**Principles:**
- Distinguish correlation from causation
- Note statistical significance (p < 0.05)
- Support every conclusion with specific numbers

**Available references:**
- `references/report_template.md` — Standard report template
- `references/statistical_methods.md` — Statistical methods quick reference

How to install

The exact contents, by fingerprint

mdr add echoyue-lp/echo-agent/data-analyst@sha256:ca56d4c93a49cf1c

The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
