A Study on Measuring the Change of the Response Results in Likert 5-Point Scale Measurement
노영희 · 2011
This study examines how and which direction respondents who participated in 5-oint Likert scale surveys change their initial responses when they are given an identical second survey after certain treatments. The research employs three identical questionnaires (first, second and third surveys)to analyze survey results based on group differences. kinds of treatment. survey purpose. and response change direction and the degree. This paper concludes that. first, it is significant that specialist groups do not change the initial sesponses compared to a general librarian group. Second, there are no differences by survey purpose: however, participants tend to change their initial responses by others' opinions rather than by previous use experiences. Third. participants who initially answered positively tend not to change their responses, and most participants who answered negatively change their initial responses in a positive direction. Fourth. when there are changes. participants change their initial responses by less than two points, and most of them change by one point. Finally, the hypothesis that middle responses change most and that participants who respond at both ends do not change their opinion was rejected by the finding that participants who answered on the negative end tend to change their initial responses in a positive direction.
