Titre / Title: VERS UNE MODELISATION DU RAISONNEMENT QUALITATIF EN STATISTIQUES
Abstract : This paper is devoted to the description, through an exemple, of a model for human qualitative reasoning in statistical data analysis. Some elements of a logical and cognitive model of qualitative reasoning in the field of elementary descriptive statitics are presented. This model concerns the experts and the novices in statistics. In order to modelize the qualitative description of statistical data or parameters, the notion of qualitative appreciation is introduced. In order to compare them, the notion of gap between two data is defined. These two notions are based on graduality and many-valued logic.
The model thus proposed allows us to tackle the notion of quantitative abstract of a statistical serie and the associated computation processes. Within this framework, a method for the approximate calculation of the arithmetic average by the novices is given.
