The problem of normality in quality control. I






Tejipar 39(2): 32-36

The problem of normality in quality control. I

Records of fill level and mass in 2 lines filling 1-litre containers with milk from a 15 000-litre tank are analysed as an example of the use of the Shapiro-Wilk test (in a Commodore-64 computer program) for determining how far data needed for quality control purposes follow a normal distribution. Each line has two HM-3 filling machines and a centrifugal pump to draw the milk from the tank, but without any special safeguards to prevent backflow.
