  • Hello all,

     

    I am confused about the sample size of Ppk calculation. I check a lot of information on the Internet and books but didn’t find out the definition of sample size for Ppk. Could anyone tell me can I use 30-32 as Ppk sample size( the total number for a lot is 1k-2k)?

     

     

    Thanks,

    Yujie
