ABSTRACT

Objective To analyze the distribution and influential factors of exam results in medical students' general surgery theory course.Methods 171 medical students were selected as subjects by cluster sampling,and the distribution and influential factors of exam results were analyzed.SPSS 17.0 software was used for statistical analysis,measurement data with (-x) ± s,and normality test with Kolmogorov-Smirnov test.Those quantitative data which do not meet the normal distribution were compared with Mann-Whitney U and Kruskal-Wallis H test.Rank transformation univariate multi-factor variance of LSD (Levene test equal error variance between groups) or Tamhane method (Levene test range error variance between groups) were compared between two groups(3-4) and the influence factors of whether the grade was good was analyzed by single factor and multi factor non conditional Logistic regression model,with the test level of alpha=0.05.Results The distribution of total exam results was normal.77 score was outlier,and the scores of female students were higher than those of male students.Scores of total exam results,multiple-choice questions and essay questions in different classes were significantly different.Data from multivariate logistic regression analysis showed that male students(OR=0.212,95％CI0.077-0.584) were unfavorable factor for good exam results,while higher scores in noun explanation (OR=12.160,95％CI1.985-74.495),multiple-choice questions (OR=9.887,95％CI2.997-32.617),essay questions(OR=18.323,95％CI6.593-50.928) were favorable factors.Conclusion The cause analysis of score's outlier and sex difference should be strengthened,and the influence of examination items on score should be emphasized.
