[edit]I've taken a couple of days off to catch up on some academic work. I'm far more competent when talking about the history of Theory in Computer Supported Cooperative Work and I finished building and testing a hierarchical difference strategy for another project[1].
Anyway, while I was away I generated some stats for the experimental users. This is my normal set of stats that I generate for measuring new user performance.
The table:
mysql:research@s1-analytics-slave.eqiad.wmnet [staging]> explain experimental_user_stats; +------------------------------+---------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +------------------------------+---------------+------+-----+---------+-------+ | wiki | varchar(50) | NO | PRI | | | | bucket | varchar(15) | YES | | NULL | | | first_event | varbinary(14) | YES | | NULL | | | user_id | int(11) | NO | PRI | 0 | | | user_registration | varbinary(14) | YES | | NULL | | | day_revisions | int(11) | YES | | NULL | | | day_main_revisions | int(11) | YES | | NULL | | | day_reverted_main_revisions | int(11) | YES | | NULL | | | day_productive_edits | int(11) | YES | | NULL | | | week_revisions | int(11) | YES | | NULL | | | week_main_revisions | int(11) | YES | | NULL | | | week_reverted_main_revisions | int(11) | YES | | NULL | | | week_sessions | int(11) | YES | | NULL | | | week_session_seconds | int(11) | YES | | NULL | | | week_productive_edits | int(11) | YES | | NULL | | +------------------------------+---------------+------+-----+---------+-------+ 15 rows in set (0.00 sec)
Some example data.
mysql:research@s1-analytics-slave.eqiad.wmnet [staging]> select wiki, bucket, user_id, day_main_revisions from experimental_user_stats limit 3; +--------+-----------+---------+--------------------+ | wiki | bucket | user_id | day_main_revisions | +--------+-----------+---------+--------------------+ | dewiki | control | 1870785 | 0 | | dewiki | post-edit | 1872620 | 7 | | dewiki | post-edit | 1872288 | 2 | +--------+-----------+---------+--------------------+ 3 rows in set (0.00 sec)
Now, let's look at activation rates.
mysql:research@s1-analytics-slave.eqiad.wmnet [staging]> select wiki, bucket, sum(day_main_revisions > 0) AS one_plus_editors, sum(day_main_revisions >= 5) as five_plus_editors, count(*) as total_users from experimental_user_stats group by 1,2; +--------+-----------+------------------+-------------------+---------------+ | wiki | bucket | one_plus_editors | five_plus_editors | total_users | +--------+-----------+------------------+-------------------+---------------+ | dewiki | control | 166 | 11 | 415 | | dewiki | post-edit | 183 | 27 | 413 | | dewiki | pre-edit | 296 | 31 | 660 | | enwiki | control | 1840 | 283 | 6171 | | enwiki | post-edit | 1808 | 319 | 5922 | | enwiki | pre-edit | 3637 | 451 | 8768 | | frwiki | control | 201 | 33 | 619 | | frwiki | post-edit | 235 | 32 | 702 | | frwiki | pre-edit | 492 | 43 | 1037 | | itwiki | control | 89 | 15 | 232 | | itwiki | post-edit | 102 | 15 | 285 | | itwiki | pre-edit | 266 | 40 | 465 | +--------+-----------+------------------+-------------------+---------------+ 12 rows in set (0.08 sec)
Now for checking significance.
