The software is a tool to evaluate the feasibility of the Data Quality Objectives (DQOs) based on cost and sample size. By entering the outputs from the DQO process, the software will compute sample sizes for several basic statistical sampling designs. This way you, the decision maker, can decide whether your decision error rates are feasible before a statistician, or someone familiar with statistical design, begins to optimize the sampling design. At the current time, the software only compares a mean against a fixed action level. In more advanced versions, software will be expanded to consider other sampling designs and other parameters of interest. This software can NOT be used to develop the optimal sampling design. The sampling sizes that are computed can only be used for comparison purposes. They are not meant to be used for the final decision.
