Bucketing criteria

WARNING: the requirements below are borrowed directly from T384372. We'll consider these Requirements "final" once the Editing and Machine Learning Teams (in collaboration with @MNeisler) align on the above and remove this warning.

Bucketing Requirements:

  • Bucketing should include both registered and unregistered users at all identified participating wikis.
  • All users, who are editing a desktop or mobile main namespace page (NS:0), at any of the participating wikis should have a 50% chance of being included/bucketed into the A/B test's control or treatment group.
  • Bucketing should be done on a per-Wikipedia basis. 50% of people within a given wiki should be placed within the control group; 50% should be bucketed in the treatment group
  • The test group should have Tone Check experience enabled while the control group should not
  • People should remain in the same test group for the duration of the test (and across sessions and pages).
NOTE: We need to specify the experiences that will be available in both the test and the control groups. For example, will all wikis in the control group have access to Multi-Check (References)?

Instrumentation-Related Requirements

  • A bucket is applied to these events so we can distinguish all events logged for the control group and the test group within the A/B test.
    • The bucket should be descriptive of the test in case there are overlapping AB tests.
  • The anonymous_user_token field is populated for unregistered users in the test.

Participating wikis

WARNING: the wikis participating wikis will not yet be final until human reviews are completed via T388471.
