Visualization of Subjective Evaluation for the Participation Attitude to the Internet of Male College Students Based on Visual Analog Scale

This paper describes the visualizations of subjective evaluation for the participation attitude to the Internet of male college students based on visual analog scale (VAS) by employing a small number of subjective evaluation measurement. 19 healthy male college students were invited as the experiment participants. In order to analyze their subjective evaluation for the participation attitude to the Internet, they were requested to answer the questionnaire on VAS (17 questions). The results showing that values based on their subjective evaluation ("applicable” or "not applicable ") for the participation attitude to the Internet have been obtained, and they are shown by using the combination of univariate scatter plots and box-and-whisker plots. Moreover, it has been discovered that the question based on the similar subjective evaluation belongs to the same cluster. This fact is supported by the results of published article analyzed in factor analysis. Under above procedure, relationships and meanings for these questions have been found by a small number of subjective evaluation measurement based on VAS.
