Non-probability sampling is a type of sampling technique whereby all the units of a population do not have an equal chance of being selected in the sample.
The primary difference. between non-statistical and statistical sampling is that non-statistical sampling relies more on the. auditorâs judgment while statistical sampling relies on quantitative measurements to determine. the sampling risk. Sampling risk is the chance that the sample audit findings are significantly.
