A) the line that goes through all the data points.
B) line obtained by minimizing the sum of the distance between the horizontal axis and the data points.
C) line obtained by minimizing the sum of squared vertical deviations of each point from the regression line.
D) line obtained by minimizing the sum of squared horizontal deviations of each point from the regression line.

Question

Quizplus · Accepted Answer

The regression line is best described as the line obtained by minimizing the sum of squared vertical deviations of each point from the regression line. This method, known as the least squares method, ensures that the line is the best fit for the given data points by minimizing the difference between the observed values and the values predicted by the line.
