This is an attempt to put all relevant information about confidence intervals into one big image, inspired by sketchnoting. Therefore, there is not too much text. If you want a more verbose version check this out. I know there is a lot of room for improvement. But for a first attempt, I am quite happy. I used inkscape for creating the image. Its convenient because it renders latex which is wanted for the formulae. But I could not add links. I am curious how you like it, so I’d be grateful if you leave me a comment with some feedback. Also, I am very interested in software suggestions, that may lead to better images. But for now — let’s focus on CONFIDENCE-INTERVALS! Yay! :)

This is it. I hope I have not confused you completely. As I already said — I’d be happy about some feedback and/or software suggestions.
