In multiple regression, to discover which independent variable has the greatest influence:
A) is to consult the coefficients to find the largest number.
B) is to consult the standardised coefficients to determine to largest number.
C) is to divide each corresponding coefficient by its standard error to determine the largest number.
D) is to consult the variance inflation factors (VIF) to find the largest number.
