(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.
Regards, Jürgen.
