Evaluation of Reliability Using RMD and ${\chi}^2$ Contingency Tests Using Correspondence Analysis in Survey Study

실증 연구에서 RMD에 의한 신뢰도와 대응 분석에 의한 ${\chi}^2$ 분할표 검정의 평가

Reliability measures of questionnaire and ${\chi}^2$ contingency tests of categorized responses are most practical tools to analyze the characteristics of subjects of survey study. This research evaluates the Cronbaha's reliability measures by using Repeated Measure Design (RMD) with illustrated MINITAB examples. In addition, ${\chi}^2$ statistics of each cell of categorized tables can be effectively interpreted with the symmetric plot of correspondence analysis. The practical example is also discussed to provide comprehensive understanding of topic.
