The need for sampling - part 1
You'll learn why auditors can't test every transaction and how they use sampling to form opinions on financial statements. This video covers the fundamental principle behind audit sampling: given the volume of transactions auditors encounter, they must select appropriate items to test based on risk assessment.

About this lesson
You'll explore the difference between selecting all items, targeting specific high-value transactions, and true audit sampling—then discover the two main sampling approaches: statistical sampling (which uses random selection to extrapolate error rates across entire populations) and non-statistical sampling (which doesn't allow for population-wide projections). The session walks through three statistical sampling methods—random selection, systematic selection, and monetary unit sampling—with practical examples showing how each works in practice. This foundational knowledge is essential for Audit and Assurance (AA) and Advanced Audit and Assurance (AAA) papers, where sampling underpins your ability to gather sufficient appropriate audit evidence efficiently.
