User:Halfak (WMF)/OB6 type of articles edited

To explore how OB6 affects the types of pages that newcomers make their first edits to, I gathered stats on the Articles where users bucketed in the experiment made their first edits.

The proportion of editors first edits is plotted by namespace and split by experimental condition.

While only 67% of first edits were made to articles, only articles make sense when asking questions with regards to page length, watchers and views. So the following analyses examined only those first edits which changed NS0 pages.

Page Length (at time of edit) edit

The length of an article is one of the best predictors of the article’s quality level. Previous work has shown that, newcomers tend to be reverted when they edit longer pages[1].

How does the length of pages first edited by newcomers differ by condition and return to status?

 
Page length density. Probability density functions are presented for the page length of newcomers first edits based on their view of MediaWiki before registering.
 
Page length mean. Geometric mean page length of newcomers first edits based on their view of MediaWiki before registering.

There could be some minor variations related to OB6 vs. control, but they are not large enough for us to be sure that they are real.


# of page watchers (2013-10-31) edit

Another way to look at the activities of newcomers is by the number of watchlisters who are watching the pages they edit.

Here, we do see some significant differences. Newcomers with OB6 tend to edit articles with more watchers in their first edit (t = -3.998, p < 0.001). This difference is relatively consistent across all return_to states.

How does the # of watchers of pages first edited by newcomers differ by condition and return to status?

 
Watchers density. Probability density functions are presented for # of watchers for pages that newcomers first edit based on their view of MediaWiki before registering.
