Data for: Online visual screening of glass-jar instant coffee packaging and colour variants

This dataset supports the manuscript “Online visual screening of glass-jar instant coffee packaging and colour variants.” Version v2.0 retains the de-identified statistical workbook and descriptive repository files from v1.0 and adds a public reproducibility archive containing executable Python analysis and verification scripts, configuration and dependency files, SHA-256 audit manifests, and revision-time rerun documentation. The workbook contains respondent-level semantic and colour-rating matrices from 503 adults in China, aggregate sample summaries, measurement diagnostics, complete-package omnibus diagnostics, colour-rating omnibus and mean/95% confidence-interval results, forced-choice summaries, anonymised raw AHP pairwise matrix values and expert-priority results from 20 experts, sensitivity diagnostics, and provenance records. The reproducibility archive includes a public-workbook verification workflow for the principal complete-package, colour-rating, forced-choice and AHP results and documents a revision-time isolated rerun in which all 33 archived derived outputs matched byte-for-byte. Respondent IDs are pseudonymous; IP addresses, exact timestamps, demographic microdata and direct identifiers are not shared. Privacy-withheld membership variables prevent reconstruction of the two consumer sensitivity subsets from the public workbook alone. Commercial complete-package stimulus images are not publicly redistributed because they contain third-party brand imagery and are subject to copyright restrictions; non-branded descriptions and schematic documentation are provided instead.
