I was recently running OC curves to determine AQL and RQL figures. Of interest was the difference in these figures when different sample sizes are used. It would be great to have the option of entering multiple sample sizes (along with population size, and allowable defects), and then plot the overlapped OC curves on one plot to help you visualise the ‘trade-off’ that exists in AQL/RQL figures for various sample size options. At present, JMP will only show curves for individual sample sizes.
