Seeing as we are now experts with straight line graphs, this week we look at how we can use Autograph to study Scatter Diagrams, Lines of Best Fit and Correlations

Autograph Video 27 – The Gradient Tool
Following on from the last couple of weeks where we have looked at straight line graphs, this time we take a look at Autograph’s excellent Gradient Function. We see how useful it can be forContinue reading
Autograph Video 26 – Parallel and Perpendicular Lines
This week we follow-up our work on straight lines with a look at how you might tackle the topics of parallel and perpendicular lines on Autograph
Autograph Video 25 – Straight Line Graphs
Here we look at two different approaches to investigating the equations of straight lines on Autograph, both of which make good use of Autograph’s excellent dynamic textboxes, and one which uses the Constant Controller
Autograph Video 24 – Easter Special
Egg-sactly what you need this time of year – an Easter themed Autograph video. Here we take our first proper look at Autograph’s very impressive 3D engine and how you can use it to createContinue reading
Autograph Video 23 – Two Tangents Theorem
In a jam-packed edition of Mr Barton’s Autograph Videos we look at all things to do with Tangents, including the Two Tangents Theorem. This also leads us to discover a slick way of marking theContinue reading
Autograph Video 22 – Alternate Segment Theorem
This week we look at our fourth Circle Theorem – the notoriously difficult Alternate Segment Theorem. Can Autograph help us understand when this theorem works and when it doesn’t? There is also a look atContinue reading
Autograph Video 21 – Angles in the Same Segment
This week we look at our third Circle Theorem – the classic Angles in the Same Segment Theorem. There is also a quick demonstration of how to set up a nice looking label for points,Continue reading
Autograph Video 20 – Animation Special
In a special edition of Mr Barton’s Autograph Videos we look at the use of Autograph’s very impressive Animation function and how you might use it in the context of angles, points and transformations.
Autograph Video 19 – Cyclic Quadrilateral
This week we look at our second Circle Theorem – this classic Cyclic Quadrialteral Theorem. After quickly constructing and demonstrating the theorem, we also have a look at a nice little extension question involving parallelograms…
Autograph Video 18 – Angle at the Centre
Whilst we are on a roll with the Angle at the Centre Theorem, why not have a quick look at a nice little twist? We can use Autograph to set up some circumstances where theContinue reading
Autograph Video 17a – Angle at the Centre
This week we take a look at how to construct Circle Theorems using Autograph, beginning with the Angle at the Centre Theorem. We also see how understanding this theorem leads us to another theorem forContinue reading
Autograph Video 17 – Circle Theorems
This week we take a look at how to construct Circle Theorems using Autograph, specifically the angle at the centre theorem. There is also a brief look at tangents, all of which should arm youContinue reading
Autograph Video 16 – Working with Grouped Data 2
I know I said last week was the last data one, but a request came through on the emails, so I thought I had best cover it whilst we are on a roll! So, thisContinue reading
Autograph Video 15 – Working with Grouped Data
In our final look at data for a while (you can have too much of a good thing) we tackle an issue with commas and how to alter the sizes of your groups. Subsribe toContinue reading
Autograph Video 14 – Valentine’s Day Special
In a special “loved-up” edition of Mr Barton’s Autograph videos, we look at a romantic (mathematical) alternative to chocolates and flowers to send to the love of your life to let them know you care.Continue reading
Autograph Video 13 – Working with Raw Data 4
In a jam-packed edition we start to look at how Autograph can group raw data for us and how this opens up a whole new set of possibilities in terms of mathematical diagrams, including cumulativeContinue reading
Autograph Video 12 – Working with Raw Data 3
Douglas Butler returns again! This time with a great suggestion for introducing the Normal Distribution via a look at the fascinating world of IQ. The also encompasses Autograph’s wonderful scaling option for nasty looking data!Continue reading
Autograph Video 11 – Working with Raw Data 2
Following a suggestion from none other than Autograph creator Douglas Butler, we take another look at some of the things you can do with Raw Data on Autograph, including quickly creating a data set. MoreContinue reading
Autograph Video 10 – Working with Raw Data
This week I deal with a request from Lucius Evans who wanted to look at some of the Statistical functions on Autograph. Here I deal with a request from Lucius Evans who wanted to lookContinue reading
