Autograph Team - Scatter Diagrams - KS4

A video tutorial from the Autograph team to teach Scatter Diagrams at KS4. It is possible to import a bivariate data set into Autograph but in this activity we are going to see how to create a dataset from points and we will then use that dataset to demonstrate least squared regression.Clicking on the web-link below takes you to all the videos in this series.

Maths GSCE: Line of Best Fit, Autograph Video

Maths GSCE: Line of Best Fit, Autograph Video

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.

Residuals: Using ICT to understand regression

Residuals: Using ICT to understand regression

Autograph, software for teaching calculus, coordinate geometry, statistics and probability is essential to make this task work. The goal is for students to understand how the regression line is chosen. Autograph has a wonderful built-in facility for showing the squares of the residuals - once seen, never forgotten.
