Work was undertaken to determine the applicability of statistical techniques for the evaluation and control of milk filling operations. It was shown that the components of the variation followed a so-called normal distribution. Thus, well developed statistical techniques can be applied. The use of gross weight appeared to be a logical control measure. The extent of deviation was found to be a characteristic of the individual filling operation. The machine filling larger containers showed a greater variation but not in proportion to the quantity filled. These statistical techniques were found applicable for the evaluation, adjustment, and routine control of filling operations for milk. Furthermore, these findings can be used as a helpful guide in establishing tolerances to be used for regulatory purposes.
