    Dada una población, cuyos individuos no se pueden describir mediante medidas cuantitativas, queda posible definir similitudes o disimilitudes entre los objetos a comparar, y luego se pueden obtener árboles de clasificación jerárquica, árbol máximo (o mínimo), grafo G3, filtrante, etc. En este trabajo se propone una representación geométrica de esta población. Ésta se basa en la construcción de un producto escalar entre los objetos del estudio, lo cual, mediante la diagonalización de la matriz simétrica, semi-definida positiva, de dicho producto, desemboca sobre una representación de la población parecida a las representaciones que se obtienen en Análisis de Componentes Principales.
