The effect of some independent variables on granting the basic application certificate using multivariate statistical analysis

الملخص EN

In this research we study of one of the methods of regression using real data for applicants for the proficiency exam (IC3), where the basic applications exam is most important test for the certificate of computer basics and the internet which is conducted by the university of Tikrit in the center for computer and informatics.

Therefor it was necessary to know and study the impact of some independent variable and the extent of their impact on the approved variable, the score of the exam and has been taken five independent variables, this is, college specialization x1, the gender of the examiner x2, specialization advanced the examiner x3, computer examiner experience x4, subscriber in turn or completed x5.

and the degree of the examiner(dependent variable) The regression method and estimation of regression equations were used according to the gradual regression methods and the standard regression method (Multiple Regression) in order to select the best regression model that includes the variables that actually affect the result of the certification of basic applications and by using the average error boxes differential measurement Mean square error (MSE)(Dean et al.1998).
