to whoever is interested in this (and I hope I didn't just repeat someone else's experiments on this):
I wanted to know if a "long" or "short" article in terms of how much readable material (excluding pictures) is presented to the reader in the front-end is correlated to the byte size of the Wikisyntax which can be obtained from the DB or API; as people often define the "length" of an article by its length in bytes.
TL;DR: Turns out size in bytes is a really, really bad indicator for the actual, readable content of a Wikipedia article, even worse than I thought.
We "curl"ed the front-end HTML of all articles of the English Wikipedia (ns=0, no disambiguation, no redirects) between 5800 and 6000 bytes (as around 5900 bytes is the total en.wiki average for these articles). = 41981 articles.
Results for size in characters (w/ whitespaces) after cleaning the HTML out:
Min= 95 Max= 49441 Mean=4794.41 Std. Deviation=1712.748
Especially the gap between Min and Max was interesting. But templates make it possible.
(See e.g. "Veer Teja Vidhya Mandir School", "Martin Callanan" -- Allthough for the ladder you could argue that expandable template listings are not really main "reading" content..)
Effectively, correlation for readable character size with byte size = 0.04 (i.e. none) in the sample.
If someone already did this or a similar analysis, I'd appreciate pointers.
