Emotional, sensory and intellectual visitor experience under augmented reality mediation at the Templo del Sol, Eliécer Silva Celis Archaeological Museum (Sogamoso, Colombia): Likert ratings and open-response corpus for lexical analysis

This dataset contains the complete response set of a quasi-experimental study measuring the emotional, sensory and intellectual dimensions of visitor experience at the Templo del Sol gallery of the Eliécer Silva Celis Archaeological Museum (MAESC), an in situ Muisca archaeological site in Sogamoso, Boyacá, Colombia. The site operates under an archaeological management plan approved by the Instituto Colombiano de Antropología e Historia (ICANH) that prohibits physical entry to the Temple, so the visitor encounter is restricted to distant visual observation.

Sixty first-time adult visitors were assigned to two conditions of thirty: an experimental group that toured the gallery with a tablet-delivered augmented reality (AR) application providing an overlaid informational layer (explanatory audio, video, music and object-level descriptions), and a control group that toured without it. Both groups completed the same 31-item post-visit instrument immediately after the tour. Data were collected between 6 and 29 May 2021.

The instrument pairs each closed Likert item with an open-ended prompt asking the respondent to justify the rating. The dataset therefore supports two distinct analytical routes: a non-parametric between-group comparison of the ordinal ratings (Mann–Whitney U), and a lexical analysis of the open responses treated as condition-partitioned corpora. The latter was performed with KH Coder using correspondence analysis of the word × external-variable table, with chi-square-based selection of the top 60 terms and a minimum term frequency of 2.

File structure
The workbook contains three sheets, representing three processing stages of the same collection event.

1. Organizada — analysis-ready matrix (60 rows × 42 columns). One row per participant, wide format. Columns 1–8 carry the identifier and demographic block: PARTICIPANTE, GRUPO (1 = control, 2 = AR), USO_APP (Sí/No), EDAD, SEXO, NIVEL_EDUCATIVO, DEPARTAMENTO, CIUDAD. The remaining columns follow a fixed three-column pattern per experiential item:

<ITEM>khcoder — the rating recoded as a single underscored token (Muy_Feliz, Me_gusta_mucho, Aprendí_mucho), the form required for use as an external variable in KH Coder.
<ITEM> — the same rating as a human-readable label.
D_<ITEM> — the participant's free-text justification of that rating.
Item prefixes: EE_ emotional experience (FELIZ, CURIOSO, ABURRIDO, CANSADO, MOLESTO); ES_ sensory experience (ESCUCHADO, OLOR, VISTO, TOCADO); EI_ intellectual experience (APRENDIZAJE). Five further open-response items record recall of specific gallery content with no paired scale: EI_OFRENDA (symbolism of the food offerings), EI_PIEZA_ORIGINAL (original Muisca pieces held in the Temple), EI_COLUMNA (the central column), EI_ASTRONOMIA (observable natural phenomena), EI_FUNDADOR (name of the archaeologist who led the reconstruction).

2. ETIQUETA IRAMUTEQ — corpus in labelled-segment format (30 rows × 28 columns). The open responses restructured into fourteen column pairs, one pair per item, with the *VARIABLE prefix convention used by IRaMuTeQ and accepted by KH Coder as an external variable marker. Within each pair, the u suffix (*APP_FELIZu) holds the AR-group responses and the unsuffixed column (*APP_FELIZ) the control-group responses. 730 non-empty text segments in total. This sheet is the direct input to the fourteen correspondence analyses.

3. Respuestas de formulario 1 — raw Google Forms export (64 rows × 36 columns). Unmodified platform export retaining the original item wording, the consent item, the screening items (nationality, prior visit, app-installation habit) and one item (y. De lo que aprendió qué fue lo que más le gustó) not carried into the analysis matrix. Retained for provenance: it documents every transformation applied in reaching sheet 1.

Scale coding
Dimension    Anchors (low → high)
Emotional    Nada / Poco / Medio / [emotion] / Muy [emotion]
Sensory    No gusta nada / No me gusta / Indiferente / Me gusta / Me gusta mucho
Intellectual    No aprendí nada / Aprendí poco / Indiferente / Aprendí / Aprendí mucho
Scales are ordinal and were analysed as such. Reverse-worded emotional items (ABURRIDO, CANSADO, MOLESTO) are not reverse-scored in the file; a higher value denotes more of the named emotion, not a better experience. Users computing composite scores must recode.

Completeness
Ratings are complete for all emotional items and for ES_ESCUCHADO (60/60). Item-level missingness elsewhere: ES_OLOR 58/60, ES_VISTO 59/60, ES_TOCADO 56/60, EI_APRENDIZAJE 57/60. Open-response completeness ranges from 49/60 (D_EE_MOLESTO, EI_OFRENDA, EI_ASTRONOMIA) to 57/60 (D_EE_FELIZ, D_EE_CURIOSO). Open responses average 6–15 words. Missing values are empty cells, not sentinel codes.

Where the associated article reports a single N per variable, that value is the smaller of the two group counts, which is the effective N for the Mann–Whitney comparison. The per-group counts in this file reproduce those values exactly.

Reuse
The dataset is self-contained and requires no proprietary software. Sheet 1 supports replication of the ordinal comparisons in any statistical environment; sheet 2 can be imported directly into KH Coder or IRaMuTeQ to regenerate the correspondence biplots. All text is Spanish; the associated article reports English translations of the extracted terms and states this explicitly. Researchers reproducing the lexical analysis should work from the Spanish originals, since lemmatisation and stop-word behaviour are language-dependent.

Beyond replication, the corpus is reusable for cross-site comparison of visitor discourse at access-restricted heritage sites, for methodological work on lexical versus scalar measurement of experience, and as Spanish-language training or teaching material for correspondence analysis of short open-ended survey responses.

Ethics
Data were collected under written informed consent, following the Belmont Report (1978), Colombian Resolution 8430 of 1993 and Law 1090 of 2006. The study was classified as minimal risk. Participation was voluntary and uncompensated beyond waived museum admission. No direct identifiers were collected. This release has been de-identified as described in the accompanying README; see that file for the specific transformations applied.
