Audit Results Report

Selected Audit Units

A total of 2 audit units were selected for the audit. Some audit units were randomly selected, as part of a contest that was randomly selected for a risk-limiting audit. Other audit units were manually targeted as being of interest for a particular reason. The manually targeted units are listed after all the randomly selected ones.

The randomly selected units were chosen according to a plan that incorporated the auditing statistics described on the Contest pages (linked to from each audit unit). It selected the appropriate number of units for each selected contest randomly, but with their chance of selection proportional to their size (the number of "contest ballots" - ballots on which the contest appeared). That was done as follows. First, election officials came up with the following 15 rolls of 10-sided dice: 123456789012345. The random selection was then based on the "Sum of Square Roots" pseudorandom number generator, using the dice throws for the random seed value. That means that you can check each and every step that led from the statistics and dice throws to the final selections with a simple calculator.
