Hi folks! First time poster here.
One of our suppliers recently FAXed over some parallelism data (using DataMyte/Quantum SPC). I manually copied the raw data over into MINITAB (our software package) and found (not surprisingly) the data is not normal (A^2 = 6.95, N=0.000). I was taught that if the data was not normal I should not do any further statistical analysis.
I have no reason to believe their Quantum data is invalid, but I cannot confirm their Ppk values using MINITAB. What to do?
Thanks in advance for your thoughts.
