Quantitative Analysis for Variance within Group in Medical Informatics Practice

Abstract

 The purpose of this study was to analyze quantitatively the learning behavior in the group in medical informatics practice, and to clarify students behavioral pattern. Data analysis was learning attitude survey questions that consists of nineteen items. The analysis performed homogeneity analysis, and the two-dimensional representation of the eigenvectors of members of each group were measured as a closed polygon on the coordinate space. Distribution of responses of a group can be understood by the polygon area. The result showed quantitative changes in thinking during exercise by displaying the distribution of polygons in the group answers. The area of the polygon will be a unified and conscious decision, but the selectivity between individuals can also be understood to challenge for a unified decision-making process even larger area. Students will acquire knowledge through some exercises, this analysis revealed that one end of a unified thought process in the group during their knowledge acquisition. Motivation to continue exercise in the process can be discussed quantitatively decisive action against the self-determination, it became possible to perform a proper teaching to students from the present results.
