In choosing the "best-fitting" line through a set of points in linear regression,we choose the one with the:
A) smallest sum of squared residuals
B) largest sum of squared residuals
C) smallest number of outliers
D) largest number of points on the line
E) None of these options

Question

Quizplus · Accepted Answer

The best-fitting line in linear regression is determined by minimizing the sum of squared residuals, which measures the distance between the observed values and the predicted values of the dependent variable. Therefore, the answer is A, the choice with the smallest sum of squared residuals. The other options are not relevant for determining the best-fitting line.
