We give a first comparison between the Principal Component Analysis PCA ("one of the oldest and best known techniques of multivari- ate analysis" according to I.T. Jolliffe) and a very young algebraic technique for the visualization of data namely the Formal Concept Analysis FCA by applying both methods to Repertory-Grid-Tests. We demonstrate the efficiency of these methods using the a particular grid of a 24 years old patient suffering from bulimia nervosa.
