Abstract

Las escalas cualitativas formadas por términos lingüísticos son utilizadas por diversas disciplinas para determinar preferencias y diversos aspectos de la vida de los individuos. Aunque es habitual asignar números a las categorías de respuesta de estas escalas, no es adecuado utilizar codificaciones numéricas cuando los individuos perciben proximidades psicológicas distintas entre las categorías consecutivas de la escala, es decir, cuando las escalas cualitativas no son uniformes. En este trabajo se propone un procedimiento ordinal para jerarquizar un conjunto de alternativas a partir de las valoraciones mostradas por un grupo de individuos mediante una escala cualitativa no necesariamente uniforme. Dicho procedimiento está basado en las proximidades ordinales entre las categorías de respuesta de las escalas. El procedimiento propuesto se ilustra con un ejemplo tomado del Barómetro del Centro de Investigaciones Sociológicas (CIS) de mayo de 2011. || Qualitative scales formed by linguistic terms are used by different disciplines to determine preferences and different aspects of individuals’ lives. Although it is usual to assign numbers to the response categories of scales, it is not suitable when individuals perceive different proximities between the consecutive categories of the scale, that is, when scales are not uniform. In this paper, an ordinal procedure is proposed to order a set of alternatives from the assessments given by a group of individuals through a qualitative scale not necessarily uniform. This procedure is based on ordinal proximities between the response categories of scales. The proposed procedure is illustrated with an example taken from the Barometer of the Center for Sociological Research of May 2011.
