Population means that the entire of set of data which sample are selected. The objective auditor apply for audit sampling is to provide a reasonable basis for auditor to draw a conclusion about population from which sample…show more content…
Statistical sampling can be classified with three criteria: 1) the sample size must be determined objectively or quantitatively, 2) the sample must be selected randomly and 3) the sample result must be evaluated mathematically. Statistical sampling is appropriate when the population is made up of large number of similar transaction and internal control is good, if internal control is poor the auditor may have difficult errors in advance so may use non-statistical sampling. When auditor want to evaluated sample result statistically with a substantive test, the auditor should determines the most likely estimate of the price amount of error in the population and calculates the range within the true. In test of control the auditor must finds the error rate of sample and then determine how high the actual error rate could be, at a particular level of…show more content…
In non-statistical sampling those items that the auditor believes will provide the most useful information are selected. On the part of the internal control system, auditor will use statistical sampling when internal control is good and if internal control is poor it is appropriate to auditor use non-statistical sampling, Summarize between statistical sampling and non-statistical sampling is for statistical sampling is appropriate when using a random selection, systematic selection, probability proportion of size and monetary unit sampling. Non-statistical sampling is appropriate when using a two method which haphazard selection and block
