Notes:
Four grape juices differing in amount of added citric acid were examined by paired comparison by 72 tasters. Some judges preferred sweet and some preferred acid juices, causing pronounced and progressive changes in the frequency distributions of the preference ratings. The correlation coefficient between variances and acid differences was 0.98. The direction and degree of preference was much more consistent for larger differences in acid. Mathematical models developed by other authors for analysis of paired comparison data are of doubtful validity or awkward in application to the present data.
