Abstract

La méthode des doubles différences est une méthode quantitative quasi-expérimentale permettant d'évaluer l'impact d'une intervention grâce à la constitution de groupes de comparaison et à la mesure de l'évolution d'un résultat entre un moment initial pré-intervention et un moment ultérieur où seulement un des deux groupes a reçu l'intervention. Cette méthode est très utile pour l'évaluation ex post de l'impact d'une intervention.
