Does anybody use Mini Tab or similar.
I am having a problem calculating Cp and CPK values for unilateral tolerences. I just download the 30 day trial of Mini Tab and I have absolutley no idea how to even get started. I have not used Mini Tab before and I passed the Six Sigma Green Belt program back in April and I am heading up an entire Process Certification program at my place of employment. I have excel spread sheets to help me out with doing the calculations except unilateral tolerences do not have normally distributed data, which works with these basic spreadsheets. Does anybody have any basic aids for unilateral tolerences??
Thanks in advance
