68 Chapter 3 t-test for paired samples (in case of normal distributed data) was used to compare differences in results between the pre-intervention and post-intervention simulation scores. Linear regression analysis was performed in order to identify factors influencing simulation scores. Statistical significance was set at p <0.05 based on a twotailed comparison. Due to the level of multiple comparisons a Benjamini-Hochberg procedure was performed critical value for a false discovery rate of 0.20.
