Nominal Scaling Undignified? until the phenomena of any branch of knowledge have been subjected to measurement and numbers, it cannot assume the status of dignity of a science" Sir Francis Galton,Father of and psychometric experimentsPsychometricExperiments, (1875) 9.

Dendrograms Recursive pair-wise visualization of a distance matrix. 40 U.S. cities. Neighboring branches are closer. 14. Clustering by Word Top 64 words agglomeratively clustered using Kendalls tau for the correlation matrix. 15. Unrooted Phylogentic Tree Minimize the length of the branches. Top 32 Keywords, 25% also in online color naming experiment. 16. Clustering by Substrate 17. Thinner, Plain Papers 18. Dull, Semi-Gloss, Papers 19. Thicker, Glossy Papers 20. TexturedPapers 21. Transparent and MetallicMedia 22. Words vs. Measurements 23. Summary Anchored elicitation of unconstrained natural language descriptions of the visual and tactile perceptual properties of print substrates can be used to create a clustering of samples by word and vice versa.
