The aim of this paper is to propose and present adaptations of unfolding analysis for symbolic data. In the article, the basic terms of unfolding analysis and symbolic data are presented. The paper presents two approaches – the internal hybrid approach and the external symbolic-numeric approach. In the empirical part, the external symbolic-numeric unfolding for LCD brands is presented. Symbolic multidimensional scaling R source codes were written by authors.
