[EpiData-list] testing of quick guide for SPC graphs

Dear All As part of telling of the most recent implementation of SPC Control graphs while attending a quality assurance conference/forum in Berlin (http://internationalforum.bmj.com/) last week I produced a "Statistical Process Control Graphs in 5 minutes" - a link is placed near the top on epidata.dk.

Please comment whether you find the text appropritate. (e.g. whether it should be 10 rather than 5 minutes). See front page of EpiData or this direct link: http://www.epidata.dk/downloads/spc5min_epidata.pdf
