Abstract
Regarding that the essential quality of the rating score kept by the rating scale indicates only a relative condition in the relation of objects' gradation, I scrutinize by means of ratinng of personality traits
(1) That concerning the rating score kept by the rating scale, in so far as gradation of the scale is not objectively laid down, is no significance in the absolute score by that scale, but in the very relationship between grades in two rating scores or more.
(2) However, that no one can at present resolve what method is most adequate to distinguish such relative gradations.
(3) That the coincidence or the difference between these gradations may be most explicitly seen in the utmost score of each grade. Therefore, the coincidence or the difference in the standard of valueithas to be considered by making a clue of the above thing.
(4) And that it is to be noticed that the valuation on such a material as used here has no reference to the coincidence or the difference in any standard of value from the point of view of experts. The problem is here limited in the comparison, resutling from rating, between subjects or groups of subject.
