The method of visual evaluation is frequently used, as is the ranking method, because it is a relatively simple means of evaluation. However, in order to measure a ranking method according to the rule of "attaching ranking", results are given with an ordinal scale. The size relation of the scale is guaranteed, but the interval values. Therefore, the average value does not have any mathematical meaning. In order to compensate for these problems, we attempted to determine the right method of analysis for ordered data and examined the normalized-rank method, which can compute a more advanced distance scale, and its method of analysis. The concept of a scale was introduced in order to carry out analysis suitable for the purpose of visual evaluation. Consequently, the reliability of the ranking method was improved.
