Manual on Presentation of Data and Control Chart Analysis: 8th Edition (ASTM Manual, 7) - Tapa dura

Sinopsis

A valuable reference for anyone responsible for controlling product quality! Get the latest information on statistical and quality control methods, as well as recommendations for their application in various types of engineering work. It addresses the three general objectives in gathering engineering data: · Physical constants and frequency distributions · Relationship between two or more variables · Causes of observed phenomena Part 1 discusses frequency distributions, simple statistical measures, and the concise presentation of the essential information contained in a singles set of n observations. It also includes additional information on the construction of box plots with a clearer definition of terms, as well as new sections on probability plots and transformations. Part 2 examines the problem of expressing plus/minus limits of uncertainty for various statistical measures, together with some working rules for rounding-off observed results to an appropriate number of significant figures. Part 3 covers the control chart method for the analysis of observational data obtained from a series of samples, and for detecting lack of statistical control of quality. New Part 4 discusses material on measurement systems analysis, process capability, and process performance. This important section is included to help evaluate the measurement process before any analysis of the process is begun.
