How to improve your figures #11: Do not repeat information
Do not repeat information in your visualisations. I repeat: Do not repeat information in your visualisations. Space is limited when you visualise data, and you need to make sure that every pixel is worth the space. If you repeat information in a figure, you are most likely using certain defaults and not repeating information consciously […]
Uber and irresistibly interesting data
The other day, the Guardian could report that Uber paid Alan Krueger $100,000 for a study that was positive towards Uber. The fact that the study was positive towards Uber should come as no surprise. You do not pay a lot of money for a study showing that your business is bad for the world. […]
The liar paradox in self-reported survey data
The liar paradox is the logical paradox in the statement “I am lying”. If you are telling the truth about lying, are you then indeed lying? I have been thinking about this paradox and how it might also be relevant for survey research with implications for our understanding of measurement error and the interpretation of […]

Introduktion til R #2
I 2016 underviste jeg et kandidatfag på Syddansk Universitet, hvor jeg anbefalede de studerende at lære R. R var ikke en del af faget, men de studerende fik mig overtalt til at afholde en workshop, hvor jeg introducerede dem til R. I den forbindelse lavede jeg noget undervisningsmateriale på dansk, der kunne gøre det så […]
Tips and tricks for ggplot2
Here is a collection of 50+ tips and tricks for ggplot2. Do read them as suggestions, or rule of thumbs, rather than principles and ideas that will generalise across contexts and presentation formats. Most of the tips and tricks are based upon material that is also available via my GitHub repository awesome-ggplot2. Here we go: […]

How to improve your figures #10: Do not use word clouds
In a previous post, I argued that people should not use pie charts. In this post I am going to make a similar case for word clouds. In short, I will argue that word clouds provide ‘foggy’ insights (pun intended). Specifically, I will discuss a word cloud that got a lot of attention in the […]
