Question

Which of the following statements is most correct with respect to the evaluation of nonprobabilistic sample results? ​It is acceptable to make nonprobabilistic evaluations only if the auditor cannot quantify sampling risk. ​All of the above are correct. ​It is acceptable to make nonprobabilistic evaluations only when probabilistic sample selection is used. ​It is never acceptable to evaluate a nonprobabilistic sample using statistical methods.

Answer 1

Answer: It is never acceptable to evaluate a nonprobabilistic sample using statistical methods.

Unlike probability sampling, nonprobability sampling does not give every individual item in the population an equal chance of being selected and hence the sample may not represent the entire population. Hence, it is not acceptable to evaluate a nonprobabilistic sample using statistical methods
