単変量散布図と箱ひげ図の組み合わせによる視覚化およびクラスタリングによるVisual Analog Scale を応用した主観評価解析

抄録

This paper proposes a new concept of subjective evaluation measurement based on the Visual Analog Scale (VAS). The purpose of this concept is the visualization of the sobering of subjective evaluation. And it is possible that this concept grasps the overall of the subjective evaluation. In order to realize these, this concept consists the following elements; (1)Measurement of subjective evaluation based on VAS, (2)Calculation of descriptive statistics value of the obtained subjective evaluation value, (3)Creating a box-and-whisker plot and (4) Implementation of the cluster analysis (ward method and k-means method). Under the above preparation, we verify the effectiveness of this new concept by actual subjective evaluation experiment.
