http://www.learningaboutelectronics.com/Articles/Regression-line-calculator.php WebTo draw the line of best fit, consider the following: Outliers must be ignored. The line must reflect the trend in the data, i.e. it must line up best with the majority of the data, and less with data points that differ from the majority. The line must be balanced, i.e. it should have points above and below the line at both ends of the line.
