Sampling practices of auditors in public accounting, industry, and government

Although audit sampling is a common procedure, relatively little is known about the sampling practices of auditors in public accounting, industry, and government. This study surveyed practicing auditors to determine how they: 1. planned sample sizes, 2. selected sample items, and 3. evaluated sample outcomes. Respondents in all areas of practice reported that a majority of audit sampling applications rely on nonstatistical methods for sample planning, selection, and evaluation. Despite the heavy reliance on nonstatistical methods, less than 10% of respondents reported receiving training in debiasing techniques, and no respondents reported using these techniques. Among statistical methods dollar-unit sampling is the most frequently employed technique. All respondents reported reliance on employer guidelines, and most reported reliance on sampling standards promulgated by the AICPA.
