Consider the dataset between a quantitative input variable, ? and a quantitative response (output) variable, ? . Which of the following provides an optimal fit between them - a linear model, a complete quadratic model or a complete third order model?

(Hint: You can use adjusted multiple coefficient of determination, ?2 to determine the optimal?

model. Your answers below must be accompanied by appropriate computation in Excel)?2 value for the linear model = ________________

?2 value for the quadratic model = ________________ [10 points]?

?2 value for the third order model = ________________ [10 points]?

Therefore, the optimal model is (Circle one) Linear Quadratic Third-order
