Analysis of Postgraduate Entrance Examination Performance Based on Gray Correlation Degree

In order to monitor the fairness and necessity of the postgraduate entrance examination, we adopted the gray correlation analysis method to analyze the entrance examination scores of postgraduates, explore the correlation between the total score of the first examination and the score of the second examination, and the correlation between the total score of the first examination and the scores of each subject of the first examination, in order to reveal the fairness of the postgraduate admission results and the rationality of the proportion setting of various test scores. The simulation results show that the gray correlation degree between the initial total score and other scores is within a reasonable range. The research findings provide a reference for improving the efficiency and fairness of postgraduate enrollment.
