Abstract
This communication aims to modestly contribute to the ethical, methodological, and epistemological training of students who desire to be engaged in research through field investigations to collect their data. Thus, it proposes to return to fundamental knowledge of definition, preparation and practice of a field survey. This being intended for the collection of qualitative data in particular by interview or observation, this communication further presents content analysis as an appropriate method for the analysis of the data collected with a view to producing scientific research of work.
