First class material added to the sister site
It took a bit of time writing it, but at last I finished. And now you may access it from the sister site's page
under the title "scatter plots".
This is an example of class material available for free download and use. I'm sure in this specific case I've not so much to brag of - but its usefulness is remarkable, in my opinion, independently of the writer.
Other accessible class material is more than welcome, and I'll provide more - just the time to prepare it.
If anyone of you have class material dealing with mathematics, statistics, physics and science, and wants to share, we'l welcome you! If you "almost have" but need to work on it to smooth a bit, may we do something together? If you have an idea, we all may elaborate on it and translate to material...
And, if you want to check the material, use it, inspire changes and corrections, please do!
Whatever your reaction, I thank you all in advance!
