Which two factors determine the persuasiveness of evidence? Also, how are these two factors related to audit procedures, sample size, items to select and timing?

While auditing a company, there is evidence to support a decision or conclusion. An audit evidence is the information that is gathered by the auditor and it is determined if that information pertains to the criteria that was already established. The lowest form of evidence which would not be very persuasive is inquiry.

It is not substantial. There are four audit evidence decisions and they include which audit procedures to use, what sample size to select for a given procedure, which items to select from the population and when to perform the procedures or timing.

Persuasiveness of evidence can only be determined after appropriateness of the evidence is determined and its sufficiency. These two factors are the outcome after the sample size and timing are determined.

The two factors that determine the persuasiveness of evidence is appropriateness (competent), meaning its relevance and reliability in meeting audit objectives for class of transactions and account balances. the evidence collected must be reliable for quality internal control, source of evidence and type of evidence. sufficiency of evidence is the quantity (enough) of evidence and proper sample size. this measures the level of materiality established for the engagement, the reliability of internal controls and the cost and benefit trade-off to obtain a level of assurance.
