The paper analyzes reviews of the Russian agricultural Bank (the study’s object, one of the largest banks in the Russian Federation, specializing in financing enterprises in the agro-industrial complex). We used the Mann-Whitney U statistical test, The Wilcoxon signed-rank T test nonparametric statistical test, and the Pearson correlation coefficient to compare subsamples. In the study results, we determined that reviews with a higher rating are less understandable and straightforward and contain more complex texts. Conversely, reviews with lower ratings are more specific and easier to understand. Thus, we can reject the null hypothesis that the subgroups of reviews rated “5” and “from 1 to 4” are quantitatively the same.
