Describe Each of the Four Types of Sample Selection Methods

Question

Examlex · Accepted Answer

The Answer is Four types of sample selection methods commonly associated with statistical audit sampling are:
• Simple random sample selection. Every possible combination of elements in the population has an equal chance of being included in the sample.
• Systematic sample selection. A probabilistic method of sampling in which the auditor calculates an interval (the population size divided by the number of sample items desired) and selects the items for the sample based on the size of the interval and a randomly selected number between zero and the interval size.
• Probability proportional to size sample selection. The probability of selecting any individual population item is proportional to its recorded amount.
• Stratified sample selection. A probabilistic method of sampling in which the population is divided into subpopulations, and samples are taken from each of the subpopulations.
