Data has been gathered for a specific analytical test method to start SQC. The issue is that when the data is tested for normality, using Anderson Darling, the null hypothesis can not be rejected.
-I have attached a photo to provide more information about the data.
My question is, does this "non-Gaussian-nes" mean that the test method contains some sort of bias?
PS- Sorry if there are any issues with the form of my question; please let me know if you need additional information.
