Question

Quizplus · Accepted Answer

The least squares method is used to find the equation of a straight line that gives the best fit to a set of data by minimizing the sum of the squares of the deviations between the observed and predicted values. Correlation analysis is a statistical technique used to measure the strength and direction of the relationship between two variables. The mean squares method and the most squares method are not commonly used statistical procedures.
