(2) Students add more than 1.4 million characters to
English
Wikipedia in March
Recent numbers show the huge impact that Wikipedia classroom
activities can have on our content: in March 2011, participants of
the Public Policy Initiative [3] added more than 1.4 million
characters to the article namespace on the English Wikipedia. That's
more than 960 printed pages (at 1,500 characters per page).
Moreover, an first analysis conducted by Amy Roth (Research Analyst
for the Public Policy Initiative) indicates that those contributions
improve the article quality by 60%.
Could you please elaborate on how "article quality" was assessed, or
rather measured here? What does it mean to say that "article quality was
improved by 60%"?
Thanks in advance.

Jürgen.
