Biological distances among the Japanese, the Hawaiians and the Pashtuns were calculated using the male permanent dentition. Applied coefficients of distance and similarity were PENROSE's size and shape distances, MAHALANOBIS' generalized distance, canonical variates and Q-mode correlation. And these affinities were again computed in order to produce a shape distance based on Q-mode standardization of the raw data. In addition, HAYASHI's quantification theory model IV was applied for these coefficients of affinities, and such coefficients were compared in a two dimensional space. It was consequently found in this study that the D2, canonical variates and Q-mode correlation coefficients produced better results for their determination of affinities in odontometric taxonomy of these populations. Moreover, the D2 and canonical variates being converted to shape measures through Q-mode standardization of the raw data, they also produced more meaningful results.
