Business Statistics

This highly accessible text gives students a solid foundation in traditional inferential statistics with the concepts of quality, variability, and process unifying themes. It covers three important features of data-center, distribution shape, and variation-for processes as well as for populations. The book also explores whether a process is statistically stable and show how analysis of an unstable process can easily lead to incorrect, misleading, and costly decisions. It develops control charts and uses them as a statistical tool to track processes. It also covers the techniques for measuring and understanding variation, and details its effects on costs and quality.Triola, Mario F. is the author of 'Business Statistics', published 1994 under ISBN 9780201589900 and ISBN 0201589907.
