A least squares line associated with a scatter plot of n points:Finding the Line of Best Fit Using a Graphing Utility. While eyeballing a line works reasonably well, there are statistical techniques for fitting a line to data that minimize the differences between the line and data values. …A more accurate way of finding the line of best fit is the least square method. If you draw a line of best fit, it is possible to determine the equation of the line of best fit. You will remember that the equation of a straight line is given by. \ [\large y=mx+c\] Where, m is the gradient. c is the intercept.Most likely, you are looking for the median values, and this is why sometimes the trend line is also called the median fit line. Then we find two points that appear to be on the regression line and calculate the slope.

The target age of the baby to predict his weight is 1.5 years old, which is equivalent to 18 months old, hence x = 18. The file I am opening contains two columns. The left column is x coordinates and the right column is y coordinates. the code creates a scatter plot of x vs. y. I need a code to overplot a line of best fit to the data in the scatter plot, and none of the built in pylab function have worked for me.Points rise diagonally in a narrow scatter between (0, 1) and (9, 9). A line labeled A is constant and horizontal extending from (0, 7) through (10, 7). A line labeled B increases diagonally extending from (0, 1) through (9, 9).
