NettetLine of Best Fit. We can also draw a "Line of Best Fit" (also called a "Trend Line") on our scatter plot: Try to have the line as close as possible to all points, and as many points above the line as below. But for better accuracy we can calculate the line using Least Squares Regression and the Least Squares Calculator. Example: Sea Level Rise NettetIt turns out that the line of best fit has the equation: y ^ = a + b x. where a = y ¯ − b x ¯ and b = Σ ( x − x ¯) ( y − y ¯) Σ ( x − x ¯) 2. The sample means of the x values and the y values are x ¯ and y ¯, respectively. The best fit line always passes through the … fasson hildesheim
