This page describes and links to two versions of a paper on percentage-based versus statistical power-based vote tabulation auditing by John McCarthy, Howard Stanislevic, Mark Lindeman, Arlene Ash, Vittorio Addona, and Mary Batcher. The paper is intended for anyone interested in vote tabulation auditing, from concerned citizens to policy-makers and from people with minimal mathematical skills to professional statisticians.
The latest, longer version of our paper, entitled "Percentage-based versus SAFE Vote Tabulation Auditing: A Graphic Comparison," can be found at SAFE Auditing - Revised November 2, 2007 Version - PDF
A shorter version of the paper was published in the February, 2008, issue of The American Statistician, one of the flagship publications of the American Statistical Association (see http://www.ingentaconnect.com/content/asa/tas/2008/00000062/00000001/art00002 )
A .pdf version is also available on this web site at TAS 'Percentage-Based versus Statistical-Power-Based Vote Tabulation Audits' - PDF
Although they completed major editing the last week of July, 2007,
the authors may still make small changes to the paper in the future.
Please send all comments and suggestions for improvement to John McCarthy (john@verifiedvoting.org).
The authors wish to thank all who have reviewed and commented on the paper
and helped improve it, particularly our fellow-members of the joint Verified Voting - American Statistical Association (ASA) email discussion list, which has been instrumental in encouraging work such as this paper and the recent
