Which of the following is the mathematical expression to calculate the coefficient of determination?
A) Coefficient of determination = 1 - (Unexplained variation / Total variation)
B) Coefficient of determination = (1 + Total variation ) / Unexplained variation)
C) Coefficient of determination = (1 - Unexplained variation ) / Total variation)
D) Coefficient of determination = 1 - Unexplained variation + Total variation)
