Tocompare:The coefficient of determination to determine which model a linear model or a quadratic model is better fits the data
Answer to Problem 146CR
Thelinear model is better fits the data.
Explanation of Solution
Given information:
The linear model and a quadratic model were fit to the same data set. The values of coefficients determination are
Linear Model
Concept used:
The coefficient of determination
A higher coefficient of determination is an indicator of a better goodness of fit for the statistical observations. Example shown in Figure-1.
The value of coefficients determination
The value of coefficients determination
Hence, the liner model is better fits the data as all the points of data fall on straight line.
Conclusion:
Thelinear model is better fits the data.
