The estimated mathematical relationship between dependent and independent variables derived using ordinary least squares is called the:

B) sample regression line.
C) residual demand curve.
D) goodness of fit.
E) coefficient of determination.

Question

Quizplus · Accepted Answer

The estimated mathematical relationship between dependent and independent variables derived using ordinary least squares is called the sample regression line. Option A is incorrect because covariance refers to the degree to which two variables are linearly associated. Option C is incorrect because residual demand curve is not a term used in regression analysis. Option D is incorrect because goodness of fit refers to how well the data fits the model, which is commonly measured by R-squared. Option E is incorrect because coefficient of determination refers to the proportion of the variation in the dependent variable that is explained by the independent variable(s), which is also measured by R-squared.
