Acceptance Sampling by Variables - Compare

Sampling Criteria - Lot Quality

  

For variables data, you either say that a unit meets specification or does not meet specification. So a sampled unit is either defective or not defective. So, you count the number of defectives and calculate the process quality as percent defective, proportion defective, or defectives per million.

Example Output
