There are two primary methods to classify amounts:
- Stratified using numeric ranges
- Classified according to a date value.
The purpose of the stratified attribute sampling command is to assess a population which was sampled in order to estimate an occurrence rate for the attribute being sampled. This command prepares an estimate for each strata, as well as an overall estimate for the population. Based upon this information a determination can be made as to whether further sampling is desirable.
An example of the report is available.
To perform such a test and have the results available in electronic work paper format, the following processing information is explained below:
