무선 RDD 전화조사의 타당성 검토 연구: 18대 대통령선거 사례 연구 = The Validity of Mobile RDD Survey Methodology: Case Study of Poll Data for 2012 Presidential Election

다국어 초록 (Multilingual Abstract)

This study aimed to evaluate the precision of mobile RDD phone survey methodology in election polls. For this purpose, we analyzed the data gathered by Gallup Korea before last year`s presidential election. The level of precision measured by the Chi-square revealed that actual precision was less than ideal, but the variability did not affect the variables of our interest. We also tried to determine the relationship between the quota and control variables and the dependent variable. If this relationship is strongly positive, then the survey results will be accurate even though some of the random sampling procedures were not kept. The result showed that there was a positive relationship but it was not big enough to guarantee the accuracy of the results. This is because the gap between the 1st and 2nd candidates was so small. More research is needed to enhance the relationship between the dependent and control variables.
