Considering the Preliminary Electoral Results Program (PERP) as a database of the federal elections for president of the Mexican Republic, a methodology was developed in order to find representative samples of ballot boxes installed in the election's day (quick count) in different hours, due to its characteristics of gathering of information, the PREP in the first hours forms a non-representative sample of data. In a particular way, in the election of July 2, 2006, after 3 hours of opening the PREP, it was observed that the accuracy of the process of the quick counts was better than the one obtained by the IFE. Among other things, this allows to lower the cost, to increase the confidentiality of the ballot boxes used in the sampling and to distinguish in a precise moment the winning candidate long before PREP finishes.
