AUDIT SAMPLING DEFINITIONS

parallel simulation

#NAME?

integrated test facility

#NAME?

embedded audit modules

#NAME?

test data

processed by clients computer programs under the auditor's control

mapping

monitors execution of a program

online inquiry

allows auditor or other authorized peronnel to select and view individual records and transactions

Difference estimation

#NAME?

ratio estimation sampling

#NAME?

Stratified Sampling

#NAME?

economic order quantity

enables client to minimize inventory carrying costs but does NOT assist auditor in verifying inventory quantity on hand or quality
-EFFICIENT - not effective

source code comparison program

compares the coding of the program from its last run with the original program testing for any unauthorized changes in the program

attribute sampling

...

Variables sampling

-testing the $ amount
-value in sample gives info about ENTIRE pop

MAXIMUM tolerable rate

rate above which the auditr would place less than full reliance on controls being evaluated

system sampling

-every certain # of a pop is selected
-pop needs to be RANDOM
-advantage - pop does NOT require prenumbering

sequential sampling

#NAME?

discovery sampling

testing area so crucial that ZERO pop errors can be tolerated
EX. phony employee on payroll
-used when auditor thinks the pop occurrence rate is NEAR ZERO

Block sampling

easy to implement but WORST method

unrestricted random selection

series of random numbers is identified and the random numers are matched to numbered items in the corresponding population

Methods of sampling used with Statistical sampling

#NAME?

Mean per unit

0

probability-proportional-to-size (PPS)

-OBJECTIVE - ID overstatement errors
-form of variable sampling
-does NOT use standard deviation
-focus = $ amount
-larger or more valueable items often picked more
-projected mistatement? If mistatement found, project to remainder of pop

variables sampling vs PPS

variables
-easy to EXPAND
-selecting ZERO and NEGATIVE balance is easy
PPS
-EASIER to use
-results STRATIFIED
-results in SMALL sample size
-easy to design

sampling for substantive tests

#NAME?

sampling for tests of controls

attribute sampling

check digits

#NAME?

code review

#NAME?

Structured Query Language (SQL)

Relational Database
-group related spreadsheet
-retrieds ingo through quries
Data Definition Language
-defines data base
-gives info on database structure
-maintains tables - can be joined together
-established database contraints
Data Manipulation Langua

Limit test

examines data and looks for reasonableness using upper and lower limits

Test data method

#NAME?

Normal distribution

#NAME?

Standards deviation

measure EXTENT to which the values of the item are spread about the mean

mean

measure of central tendency obtained by totaling all the values and dividing by the # of items
