Para los tres grupos los valores de asimetria y curtosis se acercan a cero, lo que sugiere la normalidad de la distribucion de las variables.
Los valores de distribucion de asimetria y curtosis se mantienen en torno a cero y en ningun caso exceden de [+ o -]1, por tanto se considera que la distribucion tiende a ser normal, tal como se espera de una medida de personalidad.
