# Analysis methods working packet

Twelve distinct reader jobs, each with three original constructed teaching cases, a full contextual guide and a blank private worksheet. Translations and alternate arithmetic cases are not additional topics, aid types, research or people. Nothing here demonstrates actual reader preference, customer payments or causal benefit.

Use each matching guide before the worksheet. Keep source definitions, units, eligibility, complete data, denominators and limitations. Missing outcomes are not measured failures; nominal Wilson intervals and missing-outcome bounds answer different questions. A declaration does not validate independent trials or a common probability, and an opt-in sample does not gain a representative population margin of error from this calculation. Do not merge a conditional interval with the sensitivity bounds.

The full questionnaire is an original draft, not a validated instrument or completed pretest. Rule-based attribution is not evidence of incremental purchases. A disclosure worksheet does not guarantee anonymity, permissions or compliance. Prediction numbers are supplied toy values, not trained forecasts or genuine prediction-time receipts.

Optional offline reproduction: with an existing Node.js installation, run: node reproduce-examples.mjs from this extracted folder. No dependency installation, account, network request or data upload is needed. The runner reads only the two included JSON fixtures and the public count-review.mjs module. It checks the supplied arithmetic and a separately attributed published six-decimal Wilson reference; it does not validate real source data or the statistical/design assumptions. The count module is generated from the same public TypeScript implementation used by the page, not from private study data or study code. No actual model is trained.

The manifest excludes itself and ZIP to avoid circular hashes. Archive extraction, CRC and source identities are checked. Keep completed worksheets private and minimal, without identifiers, credentials or private exports. The packet neither contacts people nor changes an account or tracking configuration. Sources were read on 1 November 2026; exact source scope and limits appear in each guide.
