As argued by Revel in his "games of scales" (Jeux d'échelles), the complexity of social phenomena indicates that a social reality is not always the same, depending on the analysis level. This article emphasizes that the aggregated data used in the construction of socio-economic indicators and scales of social stratification using surveys, central for the analysis of educational phenomena, offer an illusion of objectivity, since equivalent positions on these scales result in very different social experiences in real life, and require fieldwork strategies of research. The text presents the example of a research experience in the field of sociology of education from the perspective of the "game of scales".
