Abstract: Course paper grading often involves subjective factors. Teachers may introduce biases into the grading due to their preferences for certain topics, resulting in inaccurate grading results that fail to reflect the true abilities of students. Taking the grading results of the "Clinical Pharmacology" course as an example, this article investigates the analytical method for detecting topic bias in the course paper grading. A comparative analysis was performed on the differences in the scores between different topics graded by the same teacher and between the same topic graded by different teachers by calculating the vertical bias factor and the horizontal bias factor, and a scientific and feasible analytical method was established. This method can help teachers quickly discover biases in their course paper grading, thereby making the grading more objective and accurate.
