Table 2: Correlation and regression analysis of course evaluation. The correlation between the evaluation scores of the specified predictors and criteria and the corresponding regression coefficients (a) calculated for 825 evaluations of the traditional curriculum and 4816 evaluations of the modules of the reformed curriculum. The corresponding regression coefficients of the two curricula were tested for equality by z-test. (Explained variance) Proportion of the variance of the criterion explained by the predictor in the corresponding bivariate distribution; (r (adj.)) adjusted correlation coefficient; (z) z-statistic; (p) probability of the equality of the regression coefficients; (ns) not significant.
