Explanation
Stratified sampling is a technique that involves dividing a population into subgroups (strata) that share similar characteristics and then taking a sample from each subgroup. In the context of testing purchase transactions by different procurement officers, the transactions can be stratified based on the officers, ensuring that the audit team selects a sample that represents each officer's transactions. This method helps in achieving a more accurate and reliable assessment of the procurement process across all officers.
