Question: General patterns of time spent edit
What are the general patterns of time spent? Calculate averages and various percentiles, characterize the form of the distribution / histogram (cf. https://www.nngroup.com/articles/how-long-do-users-stay-on-web-pages/ )

Notes edit
The units are milliseconds so the media time is 25 seconds on arwiki and a whole 19 seconds enwiki. So, as expected, most pageviews do not entail much reading. At the 75th percentile people are reading for 60 or 70 seconds.
Removing negative extreme values doesn't change the look of the distribution very much. One pretty striking thing is the 95th percentile for Arabic is much lower than the other two languages. This may be a sign of interesting variation between Wikis.
- @Groceryheist: Isn't the median visible time rather 25 seconds on arwiki and 19 seconds on enwiki? (The above table gives 25296.0 and 19111.0 milliseconds, respectively.) Regards, Tbayer (WMF) (talk) 16:46, 28 September 2018 (UTC)
- Yep.
Weibull Survival Curve edit
The model might not be a perfect fit for the data. There are fancier versions of the weibull distribution with some more degrees of freedom that might be worth a shot.

Things I want to find out edit
- What is the proportion of mobile edits to each language edition and how does this compare to readership? - Does mobile editing moderate the gap between mobile and non-mobile editors?
