Abstract

It is common to quantify the concept of interest in the social and human sciences to test a research hypothesis. In such a case, it is strongly recommended to investigate if the procedure is appropriately designed and implemented according the research purpose since the quantification procedure highly affects the result of statistical analysis. In this work, we propose a visualization tool which enables us to check the construct validity of a measurement tool (such a questionnaire) in a concise and convenient way based on a penalized factor analysis model. We illustrate our method with numerical simulation and real data analysis.

인문사회학 분야에서와 같이 개념적인 주제에 대한 연구가설을 검정하기 위해서는 연구 대상이 되는 개념을 수량화하여 통계적 분석을 실시하여야 한다. 이러한 경우 연구결과에 대한 해석이 설문조사에 의한 수량화과정에 깊이 의존하기 때문에 연구자가 측정도구인 설문지가 연구목적에 부합하게 제대로 만들어졌는지 검정하는 것은 필수적인 과정이라고 할 수 있다. 본 논문에서는 흔히 사용되는 요인분석에 의한 측정도구 타당도 평가를 개선할 수 있는 시각화 방법을 제시하고 모의실험과 실제사례분석을 통해 그 유용성을 예시하였다.
