Résumé (EN)
The intention of this chapter is to extend the concept of frequency distribution, and the standard definitions of descriptive statistics for real-valued data, such as the empirical mean the empirical standard deviation and the median, to the general framework of symbolic variables. We denote by E={1,…, n} the set of units that are described by p symbolic variables Y1,…, Yp. The domain of each variable Y j for j = 1,…, p, is denoted by Y j and S = × j=1 p y j denotes the whole domain space. We will examine different types of symbolic variables, namely:- cases where each symbolic variable Y j is multi-valu ed or interval-valued;- including the case wher e logical rules may exist among the values taken by Y1,…, Y p
