Page MenuHomePhabricator dashboard: Determine if new layout change caused any decreases
Closed, ResolvedPublic4 Estimated Story Points


Per some comments in a thread on, there is a suspicion that the deployment of the collapsed language links has decreased the page views to the Ukrainian Wikipedia as a result of some users browsers being configured to Russian, thereby burying the link to the Ukrainian Wikipedia. Our previous analysis suggests that this suspicion is incorrect, and the page views dashboard also does not seem to indicate there has been a drop, but we should confirm whether this is really the case using statistical analysis.

Hypothesis: deployment of collapsed links to has significantly decrease page views to Let's perform whatever analysis we need to to decide whether to reject or accept this hypothesis.

Note: We recently released this new dashboard page to view any changes in the language clickthroughs from the portal page (ticket T140816)

Setting to high priority; this relates to a recent deployment, so should be done as soon as is possible. @debt, please triage accordingly. :-)

debt lowered the priority of this task from High to Medium.

We'll take a look but please be aware, that we only have about a week's worth of data to look at right not, as we only pushed the new portal page layout into production last week (Aug 16, 2016).

First draft up at:

@chelsyx Please review it when you have a chance. Thanks!

Thanks, @mpopov!

In the executive summary, I assume that the "we do have sufficient evidence" is meant to be "we do not have sufficient evidence"? :-)

Whoops! Will fix. Thanks!

There's a table (Table 2) that has missing data (at least it looks like it) in the description of the table:

  1. The following control time series:
  2. The following control time series:

...and slightly disappointed that you used the dynamic time warping-matched pageview time series but didn't reference The B-52's Time Warp song. :-P

@chelsyx & @TJones: please review the new 2nd draft:

@Deskana & @debt: Thanks for pointing those mistakes out! I've fixed them in 2nd draft.

@mpopov: comments sent in email.

@mpopov Looks great! Sent you my comments via email :)

3rd draft:

PDF version:

@TJones: getting the reference linking right like you suggested took some tinkering but I did it :D you were right, it is better this way.

@chelsyx, @debt, @Deskana, @TJones What do you think? Is this the final draft or does there need to be a 4th?

(I will remove the "3rd draft" subtitle if we agree that it's done, and I will make "Download PDF" into an actual link once the final draft PDF is uploaded on Commons.)

Overall, it looks good. I like the breakout by Ukrainian/non-Ukrainian IPs in fig 2. The ref links were worth it! :)

Did Table 1 disappear? It seems to only be a header.

I've been struggling with this sentence:

"On 16 August 2016, the team deployed the final major patch (for the foreseeable future) wherein the links to Wikipedia..."

Can it be changed to (something like) this:

On 16 August 2016, the team deployed a major patch wherein the links to Wikipedia

I also can't find Table 1 and am also curious as to why the images that are referenced aren't near where we referenced them at (embedded rather than all at the bottom of the report)?

Thanks! I've added the links to the Portal page for Analysis work.
