@ovasileva, in order to calculate the skin stats, can you confirm whether the default skins are correct for the listed wikis?

Yes, these are correct.

@ovasileva , I could not find wiki with language_code='nb', may I know which language wiki you are referring to?

@jwang this is about Norwegian, no.wikipedia.org. nb is an alias.

@sgrabarczuk , thanks. I have updated the Acceptance Criteria with the full names of the wikis.

Methodology

The non-default skin status is pulled from user_properties schema for each specific wiki. Additionally, we consider the global preference, which can override the skin setting on a local wiki. The global skin preference is pulled from the global_preferences schema in the centralauth database.

Both skin preference and global preference reflect the status as of the data collection date, which is September 15, 2023.

Editors are pulled from wmf.mediawiki_history schema. We focus on the non-bot users who have made a minimum of 1/5/60 content edits on a specific wiki between 2022-09-01 and 2023-08-31.

Please note that none of the three editor groups mentioned here are identical to the active editors group that we use for measuring core product metrics. The product core metric for active editors is defined as the number of registered users who have made at least 5 content edits across all projects in the given month. (ref: https://www.mediawiki.org/wiki/Wikimedia_Product/Data_glossary). For this analysis, edits are counted exclusively for the specific wiki.
