Data were tested using descriptive statistics (means and standard deviation), t-test to compare the scores of the components with the test value fixed at 2.5 at the 95% confidence level, and one-way ANOVA (with Levene test for the homogeneity of variances) to test the difference between co-op and non-co-op students and to test the effect of the length of experience on the variables. The Tukey post hoc range test, which is recommended for large samples (Kirk, 1982), was used to specify the variations of the means.
