The purpose of the present study is the calculation of the relative amount of contribution of the five subjects in entrance examination. First, the multiple regression equation X´= b2X2 + b3X3 + b4X4 + b5X5 + b6X6 + a is established, and then a and bi's are determined by the method of least square solution. X1 is the total score of the five subjects in entrance examination. And five independent variables are as follows : X2, X3, X4, X5, X6. Second, from the bi's thus determined, the β(beta) coefficients are calculated. And finally the relative amount of contribution of the five subjects is obtained by taking the ratio of each β(beta) coefficient to the sum of the β(beta) coefficients.
