The subject of “Statistics for Process Control” is rather broad, therefore, I am limiting my paper to three basic topics: first, the interpretation of patterns of variation using statistical control charts, second, quick and easy statistical tests, and third, a computer approach to solving complicated mathematical problems. My purpose is to present statistical techniques that an engineer or analyst can use with a minimum of difficulty. For me, these methods have proven valuable in the analysis of a variety of problems in the Citrus Industry.
