Iraqi Student Performance Prediction

Iraqi dataset is collected through applying (or submitting) questionnaire in three Iraqi secondary schools for both applicable and biology branches of the final stage during the second semester of the 2018 year. Initially, the questionnaire contains 56 questions in three A4 sheets and it is answered by 250 students (samples). Latter, 130 samples are discarded due to lack of information since pre-processing is applied to obtain the most complete information of students. After removing inconsistencies and incompleteness in the dataset, this study considers 120 samples instances with 55 features for experiment purposes. The features are distributed into five main categories: Demographic, Economic, Educational, Time, and Marks. Table (1) shows the dataset’s attributes/features and their description. As illustrated in this table, new features are introduced, such as holiday and worrying effects. The relationships between parents with schools and use of books and references by the student are also considered.

本伊拉克数据集通过问卷方式采集自伊拉克三所中学，研究对象为2018年第二学期最后一届学生，涵盖应用型与生物理科两个分科方向。初始问卷共包含56道题目，印制于3张A4纸张上，共有250名学生参与作答。随后，因预处理阶段需获取最完整的学生相关信息，130份存在信息缺失的样本被剔除。经清理数据集中的不一致与不完整条目后，本研究最终保留120份有效样本，共计55项特征用于实验研究。上述特征可划分为五大核心类别：人口统计学特征、经济状况特征、教育背景特征、时间分配特征以及成绩特征。表1展示了本数据集的属性/特征及其详细说明。如表所示，本数据集新增了假期影响、焦虑影响等特征，同时纳入了家长与学校的关联情况、学生书籍及参考资料使用情况等维度。
