Source and extract: CC BY 4.0. The extract retains all mathematics-file rows,
adds artificial identifiers, selects/renames fields, keeps the final grade G3,
and derives pass status from G3 >= 10. Full field and transformation notes: data-notes.html.

carData::Baumann is described in data-notes.html as a reference set for
desktop R. No page here loads the package, and no Baumann extract and no copy
of the package is distributed in this project. The package retains its GPL
version 2 or later terms. Its sources and the original study are described in
data-notes.html. The research article is not distributed.
HSB is not distributed by this website.

data/resource_timing.csv preserves 36 numerical records from an archived
two-factor teaching file. The educational setting, labels and
assignment are invented for Chapter 4; the scores are preserved, not newly
simulated. Retain the attribution and codebook. No new licence for the donor
data is asserted here, and the Special Practice CC0 dedication does not apply
to these archived scores. Original QMSBR descriptions/code retain the terms
above. See data-notes.html for provenance and coding.

Quarto Live release tag v0.2.0 (commit
d1459f7968efca5ccdb3cb8a993a399ec6d3e102; upstream manifest says 0.1.3-dev):
Copyright (c) 2024 quarto-live authors. MIT, with the full
notice below. The extension's unchanged upstream licence is also retained at
_extensions/r-wasm/live/LICENSE.md in the source project.
QMSBR adapts the two editor OJS templates to load command-runner.js;
the bundled upstream runtime is unchanged. The adapter adds selection and
current-command controls with persistent per-cell R objects.
Quarto-generated libraries retain their upstream notices in their assets.
