We provide supplementary materials for a paper that contributes to the ongoing debate over Likert scale experiments, in particular the issues of how to treat acceptability judgment data (as ordinal or interval) and what statistical model is appropriate to apply. We analyze experimental data on native speakers’ intuitions regarding marginal change-of-state verbs in Russian (e.g. ukonkretit’ ‘concretize’, ovnešnit’ ‘externalize’) and compare the outcomes of five statistical models including parametric and non-parametric tests.
