Distribution Trend of the Information Skills for Students Based on Visual Analog Scale and Likert Scale

抄録

This paper relates the distribution trend of the information skills for students based on Visual Analog Scale (VAS) and Likert scale (LS). The data are collected from 40 subjects. They were invited to answer LS questionnaires first, and then to answer VAS questionnaires a week later. To apply the same evaluation criteria, VAS data and LS data are transformed to ratio scales value (i.e. 0.00 to 1.00) and the subjective evaluation distribution based on LS and VAS are calculated. The experiment result shows that there exists unintended bias between LS data and VAS data. This fact is supported by the published articles. Therefore, it can be considered again that the presence of bias is affected by the difference of questionnaire. To obtain reliable conclusions, it is necessary to try this method on the results of feature study and do more investigation.
