Nonstatistical sampling does not involve statistical analysis, so the difference between nonstatistical and statistical sampling is most apparent in the step where sample results are evaluated. In nonstatistical sampling, the reviewer evaluates the sample results based on professional judgment or other nonquantitative factors, whereas in statistical sampling, evaluation is based on statistical analysis using accepted probability theory. Steps A-C are common to both nonstatistical and statistical sampling.
