FIELD GUIDE / LEARNER WORKFLOW
Arrive, investigate, hand off.
No account or local setup is required. Whether the work is self-directed or facilitated, a current desktop browser is recommended; all assignment data and code execution remain on the learner’s device.
Inspect the source register
Use the public data dictionary to understand grain, keys, reliability, clocks, known exceptions, and relationships.
Establish evidence in SQL
Run the starter query, inspect counts and grains, then replace it with your own reconciled evidence layer. Query results are limited to 1,000 displayed rows; the engine evaluates the full assignment data pack.
Use Python for analytical work
Load the same named tables with `from analyst import table`, then use Pandas, Matplotlib, SciPy, or scikit-learn. Matplotlib figures appear directly below the worksheet; no file paths or data uploads are required.
Keep reasoning separate from conclusions
Use scratch notes for assumptions and open questions, append concise evidence records, then write the decision-ready conclusion in Final Brief.
Export the handoff
Download one .analystcase file containing SQL, Python, scratch notes, the final brief, evidence, captured outputs, versions, and hashes. Keep it for your own record or share it for grading, coaching, or peer review.
