How do u do a line of best fit on a scatter graph?
see if there are anomalous results (ones that dont really fit the trend), circle and ignore them (label as anomaly). Then do a line with your ruler so there are an equal number of points on each side of the line. Read More »

It gives you a relation between x and y which minimizes the least squares error. All the points don't fit exactly onthe line, however the best fit line is the one which gives the smallest error. Why least squares? Because the total error am...
