Understanding the difference between sampling and non-sampling errors is crucial for effective auditing. The Poisson distribution is an appropriate model if the following assumptions are true: k, a nonnegative integer, is the number of times an event occurs in an interval. The underlying concept is to use randomness to solve deterministic problems. Sampling error arises because of the variation between the true mean value for the sample and the population.
