Note. a scale range 1–7; b scale range 0–10; c dichotomous 0 = no, 1 = yes; d dichotomous 0 = male, 1 = female, the two nonbinary students were excluded; e percentage of code 1. Bivariate associations including one or two dichotomous variables were also investigated with t-tests and χ2-tests, respectively. These analyses revealed the same results as the Pearson correlation analyses. (*) p < 0.10, * p < 0.05, ** p < 0.01, *** p < 0.001.
