title: [Development of an experimental methodology: hypotheses and variables].
abstract: In this methodological paper, we present the elaboration of the experimental design, central stage of the research cycle. First, we focus on the hypothesis elaboration from the research question. Then, we detail the hypothesis operationalisation by the means of the choice of variables. Finally, the experimental controls and the factorial designs are presented.
