Quizplus · Accepted Answer

The least squares method is used to find the equation of a straight line that provides the best approximation for the relationship between the independent and dependent variables. This method minimizes the sum of the squares of the residuals between the observed values and the predicted values of the dependent variable. The other options, correlation analysis and mean squares method, are not specifically used for finding the equation of a straight line. The option "most squares method" is not a commonly used statistical method.
