The article presents a quantitative data analysis in the setting of online university teaching. The research assumed a positive correlation between the intensity of the interaction among e-tutor and students correlated with the final evaluation. The analysis involved 248 students and considered 2845 interactions. The data showed a weakly negative correlation, thus falsifying the starting hypothesis. This preliminary work highlighted some points of attention already known in the reference literature with respect to the predictive capabilities of data analysis for the research on learning activities: 1) quality and integration of the data analyzed; 2) attribution of a pedagogical sense to the results of the analysis.
