Abstract:

To enhance test achievement evaluation in learning and teaching, we have conducted multiple linear regression analysis in multiple linear statistical analysis. A regression model of test achievement evaluation was established after the index was quantitated. The relationship between national cet4 test scores and ordinary test of students was analysed. A mathematical model of multiple linear regression is established based on the performance evaluation, and the regression coefficient values are obtained. We checked the regression model and the coefficients. The results show that the model is suited for the case. The model can evaluate the given data, and can predict the students band 4 examination results according to student's final exam reasonably when some conditions are known.

Key words: multiple linear regression, significance test, test scores
