The perceived gender ratio of 422 role nouns was evaluated by Chinese- (N = 80), Finnish- (N = 77), and Russian-speaking (N = 135) students using an 11-point rating scale with counterbalanced scale anchors. Data were collected online between 2015 and 2019, via an anonymous self-administered questionnaire. This dataset contains nine files; one PDF/A containing all of the role nouns used and their per-language translations, one PDF/A containing screenshots showing an example of the norming questionnaire (with English used as the example language), one raw data CSV file per language, one PDF/A containing the by-role and by-language results obtained in the study, one RStudio code allowing for easy replication of how the analysis was conducted, one .txt file containing this code, and one readme.txt file.
