This essay analyzes the main characteristics of quantitative and qualitative approaches to empirical social and human research, showing the extent to which they leverage each other, the advantages of their shared use and the limitations of this relationship. This theoretical and practical work discusses the principles of each strategy and its possible cooperation, proposing, in a didactic way, this gathering. It builds on more than 20 years research experience of the author, who, jointly with her group, has combined these approaches. This text concerns only empirical research, and, due to the limited space, focuses only on some classic authors and references with their seminal theories. It is organized as follows: (1) analysis of the different rationales of quantitative and qualitative approaches, (2) principles supporting cooperation between them, (3) prerequisites for articulation, and (4) proposed operationalization of such cooperation.
