The method of least squares is a method to fit a straight line to a data set so that the sum of the squares of the residuals is a minimum. The residual is the vertical distance between a data point and the approximating curve. This is why it's called least squares.

We have an example where we find the equation of a scatter plot using this method. It's an excellent way to accurate find the equation of a line. Going outside the square would increase the margin of error.



Hope this helps you!
