Asked to help debug an online maths question about #BoxPlots, and learnt there are conflicting interpretations of the 1st and 3rd #quartiles which matter with small datasets like teaching examples!

https://en.wikipedia.org/wiki/Quartile

It is also not easy to see from the documentation which any plotting library actually uses, e.g. seaborn https://seaborn.pydata.org/generated/seaborn.boxplot.html

Are box plots the etymology for "outlier"? Anything that lies outside the whiskers?

I have a problem with this article, because it attacks #boxplots for being bad at representing a distribution (duh) without mentioning that their principal purpose is to identify outliers.

#statstab #13 A Critical look at Boxplots

Thoughts: It is good to remember that all forms of data summarising comes with drawbacks. #boxplots are ok, if the data matches their assumptions. Use with caution ⚠

Drawing Boxplots is so Simple in Python!

Drawing boxplots in Python is so simpel. Therefor we just need the pandas library, a DataFrame and the plot() function!

#Boxplots sind eine großartige Möglichkeit, um die Verteilung von #Daten auf einen Blick zu verstehen. Mit nur einer Box und ein paar Linien können wir schnell sehen, wo sich die meisten Daten befinden und wie weit sie auseinander liegen. 📊👀

It doesn't matter how many times you say in class that #boxplots are not good and that there are better alternatives. You still get to see boxplots in a few assessments! :D
