The edited data are rarely used directly; they are subjected to grouping (130-7) and tabulation (130-6*), and this normally leads to a presentation in the form of statistical tables (131-4). These may be the outcome of sorting ¹, either manual or mechanical, resulting in the reorganization of the elements in a set according to predetermined rules, or more simply of a systematic count of the elements presenting a selected characteristic. The choice of elements or of characteristics may be based on the values of one or several quantitative attributes, or on the modalities ² of one or several qualitative attributes. Few studies can do without computation, simple or complex, isolated or repetitive, and the computer (225-2) now allows calculation that would have been too lengthy by hand. These capabilities have led to the development of techniques of data analysis ³. Deterministic and stochastic models (cf. 730) often require considerable computations, and so do simulations (730-6).
