Data analysis
Statistical analysis was performed with SPSS version 21.0. Pre- and post-simulation MCQ test scores, simulation scenario test score, and satisfaction survey responses were summarized by descriptive statistics. Data were analyzed by the Kolmogorov–Smirnov test (K-S test) to assess normality and were expressed as mean ± standard deviation or median and interquartile range (IQR). The Mann–Whitney test was used to analyze differences between the two groups in pre-simulation test scores, post-simulation test scores, simulation scenario test score, and satisfaction scales. The Wilcoxon's Sign Rank test was used to analyze the difference between the pre-test and post-test scores in each group.
