A)the same as the error term in a linear regression

Question

The coefficient of determination, r squared, is ____.
A)​the same as the error term in a linear regression
B)​a number that indicates how well data fits the statistical model
C) a number that must be close to zero to be useful
D) ​the same as the slope of the linear regression

Quizplus · Accepted Answer

The coefficient of determination, r squared, is a number that indicates how well data fits the statistical model. It is a value between 0 and 1, with 1 indicating a perfect fit and 0 indicating no relationship between the variables being analyzed. Option A is incorrect because the error term in a linear regression is not the same as r squared. Option C is incorrect because a coefficient of determination close to 1 is better, not close to 0. Option D is incorrect because the slope of the linear regression is a separate value calculated in the regression equation.
