WebThe correlation structure was examined by the multivariate techniques of R-type cluster analysis and direct oblimin factor analysis. Results. Cross-tabulations between tests and retests gave highly significant values of chi-squared (P ≤ 0.0001) for most items in all versions of the scale. WebSmoothness in the mouth and moldability by touch were strongly and positively correlated (R=0.88). Firmness in the mouth was well predicted by hardness by touch (R2=0.85). The matooke samples were ranked into two sensory clusters by agglomerative hierarchical clustering (AHC).
