Variables Sampling Plan for Lot Average

BIS.Net Team

Variables acceptance sampling plans are used when quality characteristics are measured on a continuous scale. Variables sampling plans tend to be more efficient than Attributes Sampling plans with a much lower sample size.

A Variables sampling plan for the lot average (or batch) protects against the receipt, or release of lots whose lot average must not exceed or fall below an unacceptable level.

This plan requires for you to specify acceptable and unacceptable levels for the average, including producers and consumers risks and known standard deviation. The unacceptable level is the worst that can be tolerated.

The sampling plan is operated by taking the required sample size and accepting the computed average falls within action limits and rejected if the computed average falls outside the computed action limit.

The BIS.Net Acceptance Sampling Plan App provides an OC CURVE and the Sampling Plan for its output, such as shown below.
