Random Sampling – Is an auditing method that basically means that all sampling units in the auditing population will have an equal chance of being selected for evaluation, or that no bias would have played a role in what was selected.

Systematic Sampling – Involves selecting sampling units using fixed intervals between selections, the first interval having a random start. This method is often referred to as interval sampling. This is because this method is where the auditor will take the number of sampling units in a population and divides this into the sample size to give a sampling interval. For example, if an auditor is auditing sales invoice where the sampling interval is 20, the auditor will determine a starting point for sampling and sample every 20th sales invoice thereafter. Non-Statistical Sampling Methods:

{text:list-item} {text:list-item}

What is the importance of defining the population when performing audit procedures? How will this affect the sample size? How will incorrectly defining the population affect the sampling unit? The auditing population is the whole set of data for auditors to test in order to reach their final auditing conclusion. Auditors need to determine a population in which...
