Substantive Evidence (Statistical sampling) Flashcards
attribute sampling
concerned with proportion of a population that either has or does not have a particular attribute
attribute sampling done in multiple ways
- hypergeometric
- binomial
- poisson
hypergeometric
sampling without replacement from a population of finite size. Probability of finding an error depends on the attributes of previous selected units
binomial
sampling from infinite population or without replacement
poisson
continuous population where error probability is very small (example probability of car accident)
upper precision limit
the level of possible error/audit difference in the population being tested at a particular risk level
difference monetary unit sampling and attribute sampling
monetary unit (each euro in population) and physcial unit (invoice)
MUS
to determine whether an account balance is materially misstated. Random selection of montary units from a population and results in a sampling comprising the physical items within which the selected montary units reside (recognized as the preferred substantive sampling method for auditors in most circumstances)
MUS advantages
- emphasizes larger balances
- several samples tested in one item
- easy to apply
MUS disadvantages
- negative and zero balances can not be selected
