Final Exam

Question 1

Statistical sampling

Answer 1

an approach to sampling where random selection is used to select a sample and probability theory is used to evaluate the sample results

Question 2

Non-statistical sampling

Answer 2

any sample selection method that does not have the characteristics of statistical sampling

Question 3

Statistical sampling

Advantage and Disadvantage

Answer 3

An advantage of statistical sampling is that it allows an auditor to measure sampling risk; that is, the risk that the sample chosen by the auditor is not representative. Sometimes a disadvantage of statistical sampling is the cost involved in using this technique.

Question 4

Non-statistical sampling

Advantage and Disadvantage

Answer 4

An advantage is that it is easier to use than statistical sampling, is lower cost, and allows an auditor to select a sample that they believe is appropriate

Disadvantge is that it is a not a random sample so it can be scewed

Question 5

Most audit firms use a combination of _______ and ____________ as both methods provide appropriate audit evidence and allow the auditor to form a conclusion on the items being tested

Answer 5

statistical, non-statistical sampling

Question 6

Examples of Non-statistical sampling

Answer 6

Haphazard selection
the selection of a sample without use of a methodical technique

Judgemental selection
the selection of items that an auditor believes should be included in the sample for testing

Question 7

Examples of Statistical sampling

Answer 7

Random selection
process whereby a sample is selected free from bias and each item in a population has an equal chance of selection

Systematic selection (Inerval)
the selection of a sample for testing by dividing the number of items in a population by the sample size, giving the sampling interval (n) and then selecting every nth item in the population

Block selection
the selection of items that are grouped together within the population of items available

Question 8

Tests of controls (controls testing)

Answer 8

the audit procedures designed to evaluate the operating effectiveness of controls in preventing, or detecting and correcting, material misstatements at the assertion level

Question 9

Preventive Control

Sales occur that are not collectable.

Answer 9

The computerized accounting program will not allow a sale to be processed if a customer has exceeded its credit limit.

Question 10

Preventive Control

Fictitious employees are paid.

Answer 10

Amounts cannot be paid to employees without first matching a valid social insurance number to the employee master file.

Question 11

Preventive Control

Sales are recorded at the wrong amount.

Answer 11

Sales invoices are automatically priced using a master pricing file

Question 12

Preventive Control

Transactions are classified and coded to incorrect accounts.

Answer 12

The account coding on each purchase order is checked by the computer using a table of valid account numbers, and then various logic tests are performed by the computer.

Question 13

Testing Controls

Answer 13

Enquiry
Observation
Inspection of physical evidence
Re-performance

Question 14

Enquiry

Answer 14

This technique involves the auditor asking questions to determine how the control is performed and whether it appears to have been carried out properly and on a timely basis. For example, the auditor may ask the employees who prepare the sales invoices how they determine when to prepare the invoice and how they ensure that the revenue is recorded on a timely basis.

Question 15

Observation

Answer 15

This technique involves the auditor observing the actual control being performed. For example, they may observe the preparation of an invoice to determine if the related shipping report has been received.

Question 16

Inspection of physical evidence

Answer 16

This technique relies on the auditor testing the physical evidence to verify that a control has been performed properly. For example, the auditor may select a sample of invoices to determine if the related shipping document is attached.

Question 17

Re-performance

Answer 17

This technique involves the auditor re-performing the control to test its effectiveness. For example, the auditor may test the application controls for accessing the billing module to ensure an unauthorized employee is unable to generate invoices (and that an unauthorized attempt to do so is recorded on an exception report).

Question 18

Understand how to interpret the results of testing of controls

Answer 18

If the controls tested are considered to be effective and can be relied on for the purposes of reducing overall audit risk for a particular significant account and assertion, the level of additional substantive testing required is reduced. If the controls tested are considered to be ineffective and are not able to provide any audit evidence that reduces overall audit risk for a particular significant account and assertion, the level of additional substantive testing that is required is increased
