Just out of interest, if the maximum value is 5, and (for example) the
"neutral" mean is 3.6, how can the standard deviation be 1.82?
Wouldn't that allow values up to 5.42?
If that's an effect of extreme skewing, maybe the median would be
better suited to give a "common" value?
Cheers,
Magnus

Everyone,
As some of you may know, we launched an experimental Article Feedback
feature as part of the Public Policy Initiative last week. The "Article
Feedback Tool" enables readers to quickly assessthe sourcing, completeness,
neutrality, and readability of a Wikipedia article on a five-point scale.
It is currently deployed on about 300 articles [1] in the area of Public
Policy on the English Wikipedia. More details may be found on the blog post
[2] as well as the post on Foundation-l [3].
We've been capturing the ratings data and have some early analysis to share
around the types of ratings users are providing. There are some interesting
differences between anonymous and registered users:

The dump of the article-level data is also available [4] for those who are
interested.
If anyone would like to be involved in the ongoing research and evaluation
of this tool, please sign up on the Article Feedback Workgroup page. [5]
