What is attribute sampling?
Used in test of controls (Yes or No test)
Evaluates if specific control is operating effectively by testing for presence or absence of an attribute.
What does attribute sampling not test for?
Does not include dollar amount transaction testing
Larger dollar amounts higher chance of selection for testing (over small dollar amounts)
What are the four focuses of test of controls for attribute samplings?
Authorization (approvals before processing testing)
Completeness (all transactions recorded testing)
Accuracy (correct amount testing)
Validity (legitimatize transaction testing)
What is variable sampling?
Used in substantive testing to estimate misstatements (dollar transactions testing)
Applied to account balances or transaction amounts (for material misstatements monetary)
What does variable sampling not test for?
Larger dollar amounts higher chance of selection for testing (over small dollar amounts)
What is Monetary-Unit-Sampling (MUS) also called Probability-proportional to size (PPS) sampling used to test (give examples)?
Focuses on overstatements
Statistical testing giving larger dollar items a higher chance of selection (testing existence and valuation of assets)
Project dollar misstatements found in sample population
What’s the difference between statistical sampling vs nonstatistical sampling?
Statistical = Quantifies sampling risk and select a random representative sample by using mathematical formulas and probability theory.
Nonstatistical = Relies on judgement for sample selection and evaluation and does not quantify sampling risk (can be appropriate under GAAS but it lacks objectivity and precision of statistical methods)
What is tolerable deviation?
Maximum rate of failure auditor is willing to accept and still rely on the control
What is deviation rate?
Rate at which the control fails in a sample
What is the relationship between the sample size and the tolerable misstatement (if one increases/decreases the other does ??)?
They have an inverse relationship as tolerable misstatements increase (acceptance for misstatements) the required sample size decreases.
Auditor is willing to accept more errors leading to less testing
What is the relationship between sample size and expected misstatements, population variability, and audit risk (if one increases/decreases the other does ??)?
Correlated to each other so if one goes up so does the other.
Higher expected misstatements leads to higher testing sample size, population variability, and audit risk.
Can statistical and nonstatistical sampling be used for test of controls or substantive tests or quantify risk?
Yes, but statistical sampling quantifies risk that the sample doesn’t represent the population (where nonstatistical cannot).
What is the goal of variable sampling?
Estimate misstatements not control deviations
Is variable sampling a substantive procedure and a test of controls?
Part of substantive procedures but not a test of controls
What is Monetary-Unit-Sampling (MUS) also called Probability-proportional to size (PPS) sampling not suited for?
Detecting understatement or omissions since it draws only on recorded amounts
What is sample size in variable (substantive) sampling influenced by (four factors)?
Tolerable misstatements
Expected misstatements
Standard deviation
Population Size
What is the relationship between standard deviation (variability) and sample size?
The larger the standard deviation (variability) the higher sample size to achieve desirable results
