Data Analysis
We analyzed data using SPSS 19 Advanced Version. In the preliminary analysis, no
outliers were found and the scores of both the RCT and TOIEC scores were normally distributed.
The relationship among the variables with the EFL reading comprehension was calculated by
correlation analysis. The contribution of each of the variables to the discrimination among
students at different proficiency levels in the sample was examined using discriminant functional
analysis and the one-way ANOVA analysis. Finally, how these component skill variables
contributed to the TOEIC reading comprehension was analyzed by regression analysis. For all
analyses, a 95% confidence interval was maintained.
