It's also worth to mention noise-based dithering - where some noise pattern is added atop of the image and then rounding is performed. Usually some sort of blue noise is used for this approach.
Agreed - blue noise dithering is very commonly used in computer graphics because it’s cheap and great, but it might be worth mentioning that it’s a kind of ordered dithering, which is mentioned in the article.
Christoph Peters’s free blue noise textures are the most commonly used, for people who can’t be bothered running void and cluster themselves: https://momentsingraphics.de/BlueNoise.html
