How to Spot Visualization Lies

in #dataisbeautiful3 years ago

My favourite 101 collection on how to see through data visualisation trickery, thereby giving you a good set of "rules of thumb" to look at data properly. If you're really into it, there's an oldie, but goody book called "How to Lie with Statistics". https://en.wikipedia.org/wiki/How_to_Lie_with_Statistics

Great examples. Are these ones that you produced?

No I haven't made them, but for everyone who enjoys looking at data, or even just reading the news - this is a must! Source: https://flowingdata.com/2017/02/09/how-to-spot-visualization-lies/

very interesting, do you think these tricks apply to the cryptocurrency charts as well? would maybe significant for the traders

I have seen plenty of y-axis manipulation on crypto price and return graphs to stimulate FOMO and get people buying.

Absolutely! I've seen a lot of tomfoolery in the crypto world. Particularly among how newer ICOs like to report their early successes in the market. They're just using the same old tricks as you can see above usually. I'll send you one if I come across something :D

Oh my. Literally the things I learned/taught in my Information Visualization class. I brought this up in your intro post!

The biggest rule of thumb my professor taught us was Never Use Pie-charts unless there aren't a lot of sections and the differences among each is easily noticeable without having to rely on numbers in those sections. One of the most "eye opening" one for me was how people sometime change the scales on the y-axis to make the difference look enormous. So many tricks...

Anyways, thanks for sharing!

Haha N-E-V-E-R Piecharts. Not even once :)

Totally agree

I am a huge fan of Edward Tufte and the work he has done to make data visualization honest again. Unfortunately there is very little education around these topics, and I think you can add #steemiteducation or #education tags to these types of posts as well :) I think the #blockchainbi community would enjoy reading this too.

Thanks for the tips! And yes, Edward Tufte is phenomenal :)

Glad you think so too... otherwise the conversation might be rather interesting :)

very nice overview. Also in science, statistic tricks are the most common deception.
