The 29th in Mr Barton's Autograph Video tutorial series. Following on from our work on Scatter Diagrams, we take a look at how the Line of Best Fit is calculated. This provides a valuable link from Key Stage 4 maths to A Level Statistics as Autograph is able to clearly demonstrate the method for finding the least squares regression line. Below the video you will find an option to download it and play it on a larger screen, or by clicking on the web-link you can see all the videos in this series.

Great video, love Autographs use of the sum of the areas of the squares. Great visual way to help students improve their line of best fit
