a test is having reliable and valid measurement tools. The purpose of this
study is to conduct item analysis to questions for an exam which measures the
biostatistics knowledge of students and to assess the Biostatistics Program.
The study group consists of
a total of 261 students in their second year of Ondokuz Mayıs University
Faculty of Medicine. 132 (50.6%) of the students are female, while 129 (49.4%)
are male. Item analysis was assessed by using classical method and Rasch
analysis. The average value of the test which consisted of a total of 60
multiple choice questions was 47.47± 6.99; the
lowest score was 15, while the highest score was 57. KR 20 value was found as
0.86. When all the questions were analyzed with Rasch analysis, item difficulty
of 75% of the items was between -1.60 and 1.60.
As a conclusion, the exam was found to be
reliable and it was shown to be a moderately difficult exam which assessed the
knowledge of the students. Future studies are planned to assess Biostatistics
