The aim of the research is to apply the row (R) and column (C) association model from Clogg and Shihadeh [1] to rescale the parents' education variable that is two ordinal variables to be transformed a continuous variable. The study also compares the results of β in logistic regression among using parents' education as years, ordinal variables and RC association model. The results indicate the β is maximized as the RC model is conducted, which can explain more variance for parent's education variable. The contribution of this study confirms that the results will be more significant when a proper statistical analysis, such as the RC model, is considered involving parent's education variable for related studies.
