Objective　To explore the factors that affect the teaching effect of medical statistics study for clinical postgraduates and to provide a reference for further improving teaching Quality. Methods　Four hundred and eighty-nine students who had attended Medical statistics in 2013 Fall semester were surveyed by the self-designed questionnaire. The Logistic regression model was used to analyze the factors affecting the learning effect. Results　A total of 489 questionnaires were distributed and 488 valid questionnaires were returned (the return rate was 99.80%). 71.11% (347/488) were entirely in favor of giving medical statistics course while 23.98% were relatively supportive. Statistics recognition

learning motivation

finishing homework and the satisfaction of learning were the factors that affect the grades. The OR values are 1.547

1.723

1.374

1.433 for the above four factors respectively. The difference was statistically significant (P<0.05). Conclusion　In medical statistics teaching

it can improve students' performance by introducing case study

simplifying the mathematical formula

combi-ning the theory and computer statistical software practice

and improving teaching methods

which helps improve the quality of teaching.
