Fig. 3.

Online histology exam results. A) Examination results are shown in a boxplot with median and lower 25% and upper 25% quartile, for students of the second semester (n = 132), third semester (n = 170), and of the third semester without repeating students (n = 139). B) Histogram showing reached points in the exam for second semester (light green), third semester (olive green) and third semester repeaters excluded (yellow bars). C) Scatterplot with correlation analysis of age and exam performance for second semester (light green) and third semester (olive green) and given p-value. Most of the students were around 20 years, but in both semesters the age shows a significantly negative correlation with the performance in the exam. D) Gender-related differences is shown in boxplots with median, lower 25% and upper 25% quartile for both, male and female performances and both semesters.
