As one of my interests is computer programming you will find pages with source code and also with statistics. Here you can get a quick, but quite comprehensive overview of the essential statistical concepts and methods with links to online calculation pages.
A special new addition is Vibeke’s Artwork. Here you can see a large collection of artwork, which you can purchase at a low price for download to your computer.
The website includes other subjects as well as you can see if you explore the menu. There may be an ECstep for you.
This site is in constant development. I will gradually expand the site to include more important and popular topics.
The pages are responsive – they adapt to your screen’s size. So they are easy to read on any screen (computer, tablet or mobile). Please note that some YouTube videos on a page may not be visible in some countries.
