This book is aimed at students of sociology, political science, communication, international relations, public administration, communication, journalism and management, as well as data users or consumers who prefer a user-friendly introduction to data analysis in the simplest possible language. The book presents theoretical foundations, focusing on the discussion of the use of statistical methods. We provide relatively few mathematical details, for the argumentation of which we will refer to other statistical textbooks, mainly in Romanian, to facilitate direct reading.
