Research on correlation analysis between test score and classroom attendance based on linear regression model

Test score is the main criteria to measure the learning effort of students. There are many factors may improve or lower the test score or examination results, such as classroom attendance, home work, communication and interaction, teaching methods, self-learning, review, discussion, etc. It is very important to teachers and students to figure out the inherent correlation between test score and these factors. In this paper, a research on correlation analysis between test score and classroom attendance based on linear regression model is presented. Regression analysis is introduced and the curves of correlation between test score and classroom attendance are ploted based on the test score and classroom attendance records during two years. The scatter diagram and linear regression model of three courses indicate that the test score or examination results closely related to the classroom attendance.
