control-sampling

To design a control testing sampling plan, you define the testable population, select a sampling method, size the sample, and set a tolerable deviation rate. This ensures a defensible testing process by structuring these parameters into a documented rationale.

A tolerable deviation rate in audit sampling is the maximum acceptable rate of control failures. Setting this rate is a core component of sampling design, allowing you to size the sample appropriately and establish a defensible threshold for control testing.

You document a sampling memo for an audit workpaper by generating a structured artifact that records the population definition, sampling method, sample size, and rationale. This provides a referenceable document for reviewers to defend before an examiner.

Yes, you can use this to sample account-opening packets for a control test. You simply define the specific population, such as packets opened in a period, and the design process will size the sample and document the testing rationale for that group.

You need pypdf and pdfplumber dependencies to process source documents when documenting control testing samples. These libraries, along with jsonschema, support the extraction and validation required to output a structured memo conforming to a schema.

The best way to structure a population definition for risk management sampling is to clearly identify the complete set of testable items, such as all transactions in a period. This clear boundary ensures the sample size and deviation rate calculations remain statistically defensible.
