the significant results from both Kolmogorov- Simonov and Shapiro-Wilk which are higher than 0.05 .200 0.05, .765 0.005, .351 0.05.
c. Pearson Product Moment Correlation Test
Due to the fact that both of the data critical thinking ability and comprehension reading ability tends to be linear and normally distributed, the
parametric statistic that is used in this study is Pearson Product Moment. It is used to find out the correlation coefficient between two variables. The final score of
variables X and Y are presented in the following table:
