User Study Dataset for WikiQuality: A Browser Extension for Wikipedia Article Quality Assessment

Participants compared pairs of Wikipedia movie articles in two conditions: without tool support and with the support of the extension. The dataset includes responses about article selection, decision accuracy, confidence, perceived difficulty, time spent, assessment criteria, perceived usefulness of the extension, ease of understanding its interface components, likelihood of future use, and suggestions for improvement.

Structure: The dataset consists of two questionnaire files, corresponding to the unaided (Stage 1) and extension-supported (Stage 2) stages of the study, and one spreadsheet containing the anonymized responses. Each spreadsheet row represents one participant, while columns describe the assigned article pairs, decisions, correctness, ratings, selected criteria, and open-ended comments.
