The third volume of the ’30 anni di informatica archeologica’ series focuses on the quantitative approach to archaeological data analysis and explores the fifty-year evolution of Analyse des Données, starting with Jean-Paul Benzécri’s seminal 1973 work. The volume, prefaced by Tito Orlandi, features contributions from scholars directly involved in this evolution, highlighting the role and influence of the French school of data analysis, the dissemination of exploratory data analysis techniques, and their legacy in contemporary Data Science tools.
