{Computer Training Narrative} Determine the coefficient of determination quadratic model.What does this statistic tell you about this model?

Coefficient of Determination

A statistical measure that determines the proportion of variance in the dependent variable that can be predicted from the independent variable(s).

Quadratic Model

A statistical or mathematical model in which the relationship between the independent variable and the dependent variable is represented by a second-degree polynomial or parabolic function.

  • Elucidate the role of the coefficient of determination in the context of the model's suitability.
  • Apply software tools designed for statistical analysis to perform and interpret regression analysis.

Final Answer :
Since R2 = .819,this means that 81.9% of the variation in y is explained by this quadratic model.Clearly the quadratic model provides better fit to the data than the simple linear model.
