| 摘 要： | 首先，根据主成分分析法对数据进行筛选，得到影响学生学业成绩的主要因素；其次，根据贝叶斯统计理论建立贝叶斯预测模型，并利用五年级部分数据作为训练数据，从而对五年级6班学生的学业成绩进行预测；最后，对预测结果进行分析。预测结果中学生学业成绩的等级与实际成绩等级比较吻合，表明用贝叶斯模型预测学生的学业成绩是可行的。该研究结果可为教师和家长提供一些建设性建议。 |

| Abstract： | Firstly, according to the method of principal component analysis, the main factors that affect students’ academic performance are selected. Secondly, the Bayesian prediction model is established according to Bayesian statistical theory, and some data from grade 5 are used as training data, then the students’ academic performance prediction of class 6, grade 5 is achieved. Finally, the forecast results are analyzed. The student’s academic performance in forecast grade and in actual grade are coincided. The results show that the Bayesian prediction model is feasible for the prediction of student’s academic performance and provides some constructive suggestions for the education of teachers and parents. |
