Best practices for analytics, data analysis, and visualization using Python, pandas, matplotlib, seaborn, and Jupyter notebooks. Use when performing exploratory data analysis, building data pipelines, creating statistical visualizations, writing Jupyter notebooks, cleaning and transforming datasets, or implementing analytics dashboards.
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
# Analytics and Data Analysis Guidelines for data analysis, visualization, and Jupyter-based workflows using pandas, matplotlib, seaborn, and numpy. Prioritize readability, reproducibility, and vectorized operations. ## Workflow: Exploratory Data Analysis Pipeline 1. **Load and inspect** — Read data with `pd.read_csv()` or appropriate loader, check `.shape`, `.dtypes`, `.describe()`, and `.isnull().sum()` 2. **Clean and transform** — Handle missing values, fix dtypes, rename columns, filter outliers using vectorized pandas operations 3. **Explore relationships** — Use `.groupby()`, `.corr()`, and cross-tabulations to identify patterns 4. **Visualize findings** — Create targeted plots with matplotlib/seaborn; label axes, add titles, use colorblind-friendly palettes 5. **Validate results** — Run statistical tests, report confidence intervals, verify assumptions 6. **Document and share** — Structure notebook with markdown sections, clear outputs before sharing, pin dependencies ## Key Principles - Write concise, technical code with accurate Python examples - Emphasize readability and reproducibility in data analysis workflows …

How to install
mdr add mindrally/skills/analytics-data-analysis@sha256:2d200073c2490a1fThe line at the top of this page pins the label git:20261008.7682ca7, 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.
