The divisor of the standard error of estimate in a simple linear regression is n - 2.

Question

Quizplus · Accepted Answer

The divisor for the standard error of estimate in a simple linear regression is actually n - 1, not n - 2. This is because one degree of freedom is used for the slope coefficient and one for the intercept coefficient, leaving n - 2 degrees of freedom for the error term. However, the correct statement that the divisor is n - 1 still leads to the conclusion that choice A is true.
