I am trying to determine the process capability but the collected data does not follow a normal distribution; I have tried non-normal distributions that better fit the data but... I also coverted the data using Box-Cox and Johnson Transformation but since the actual physical values are powered or root squared(number scale has changed). My question: Is there any method that once the data has been transformed to be normal you can somehow present the report in the original scale? If so how can I do it?
