基于共性因子和多元回归对大学生手机使用情况与基础课和专业课成绩之间的相关性分析

Analysis of the Correlation between College Students’ Mobile Phone Use and the Grades of Basic Courses and Specialized Courses Based on the Common Factor and Multiple Regression

为了研究大学生手机使用和平时复习情况与基础课和专业课成绩之间的相关性,对山东理工大学统计学专业的学生进行问卷调查并收集到有效问卷223份。运用SPSS软件对问卷数据进行因子分析来确定共性因子,得出因子模型与因子得分函数。最后采用多元线性回归模型对数据进行拟合,得出手机是否进入课堂并不是影响学生基础课和专业课成绩的主要因素,学生成绩的好坏主要取决于学生在玩手机时的自我控制能力。

In order to study the correlation between the use of mobile phones and the review of college students and the scores of basic and professional courses, 223 valid questionnaires were collected from the students majoring in statistics in Shandong University of Technology. SPSS software was used to conduct factor analysis on the questionnaire data to determine the common factors, and the factor model and factor scoring function were obtained. Finally, multiple linear regression model is used to fit the data, and it is concluded that whether mobile phones enter the classroom is not the main factor affecting students’ grades of basic courses and specialized courses, but the quality of students’ grades mainly depends on students'self-control ability when playing mobile phones.
