We ended the week-long A/B test of the 'getting
started' tour delivered to
half the new English Wikipedians who chose a task from
Special:GettingStarted after signing up. (Results forthcoming.)
Quick update: it turns out we needed to re-enable this split test until
next Thursday, due to bug 45251.
Explanation for those interested in the challenges of A/B testing: this bug
caused a subset of users to get logged as in the test group, but not
actually delivered the tour. The group affected by this was big enough that
it meant after removing them from the list, it was not a large enough
dataset to declare any kind of statistical significance about what effect
the tour had. Ori and Matt patched in a fix and deployed today along with
some other bug fixes. I owe them both big time, and hopefully next week
Dario and I will be able to declare some results about the impact of guided
tours on editor activity.
