What is Type II Error

Audit testing objectives, frequently, are determined in the preceding audit processes: planning as well as study and evaluation of controls. IT audit test materiality influences the audit testing nature, timing, and extent. In designing tests, the in-charge auditor must choose between statistical and non-statistical testing methodologies. Compliance and substantive testing may take the form of inquiry, observation, inspection, or re-performance. Sampling method selection reflects whether audit area statistical inferences are going to occur concerning the target population. Sampling risk, acceptable error rate, and the expected extent of errors in the population are sample size consideration factors. Chapter 5 conveys how to determine IT audit test objectives, test materiality, test methods, test designs, and designing audit tests.
