Analysis of the final test paper of medical statisticsin nursing undergraduates from Peking Union Medical College / 基础医学与临床

ABSTRACT

Objective To learn the overall results of the final test paper in nursing undergraduates of Peking Union Medical College, and to provide the theoretical support for teaching quality assessment of nursing undergraduates.Methods The difficulty coefficient, the discrimination index, the reliability (Cronbach α coefficient) and the degree of coverage were analyzed based on education measurement and education statistical methods.Results The mean total score was 67.8±12.5, ranged from 38 to 95.The difficulty coefficient, the discrimination index and the Cronbach α coefficient were 0.68, 0.30 and 0.71 respectively.The rates of loss score were 33.8% for choice questions, 37.2% for completion questions, 22.5%for true or false questions and 24.8% for calculation questions respectively.Among the total 30 examination questions, the proportions of the most difficult ones, the difficult ones, the moderate ones, the easy ones and the easiest ones were 30.0%,13.3%,20.0%,20.0% and 16.7% respectively.28 examination questions (93.3%) had the best or better discrimination.Conclusions The test paper held the moderate difficulty and the good discrimination, reliability and the degree of coverage.The results of the examination accurately reflect the knowledge and ability of the students.In addition, more attention should be paidto improve the knowledge of nursing undergraduates on the importance of the medical statistics in medical scientific research.
