The most common method for fitting a regression line is the method of least-squares. This method calculates the best-fitting line for the observed data by minimizing the sum of the squares of the vertical deviations from each data point to the line (if a point lies on …

This line obtained by the least squares method gives the best estimate of a line with least sum of deviation. as calculated quantifies the spread around the regression line. The objective of least squares method is to obtain a compact equation that best describes all the data points. The mean can also be used to describe all the data points.

Your graphing calculator can find the “line of best fit” for a set of data. It uses the method of least squares, a very common method for finding the equation of a regression line. To find the equation of the line of best fit. Put your data into 2 lists, the default lists used by the calculator …
Activity overview:
One goal of this exploration is to see how the calculator finds the line of best fit, known as the linear regression model. It uses a technique called “Least Squares Regression.” If possible, project or draw the scatter plot of the data on the front board of the classroom. Have a student draw her or his line of best fit.

This would include a large part of the calculations involved in the method of least squares… In the absence of a special engine for the purpose, the solution of large sets of simultaneous equations is a most laborious task, and a very expensive process indeed, when it has to be paid for, in the cases in which the result is imperatively needed.
