Book Synopsis Quantifying Measurement by : Jeffrey H Williams

Download or read book Quantifying Measurement written by Jeffrey H Williams. This book was released on 2016-11-01. Available in PDF, EPUB and Kindle. Book excerpt: Measurements and experiments are made each and every day, in fields as disparate as particle physics, chemistry, economics and medicine, but have you ever wondered why it is that a particular experiment has been designed to be the way it is. Indeed, how do you design an experiment to measure something whose value is unknown, and what should your considerations be on deciding whether an experiment has yielded the sought after, or indeed any useful result? These are old questions, and they are the reason behind this volume. We will explore the origins of the methods of data analysis that are today routinely applied to all measurements, but which were unknown before the mid-19th Century. Anyone who is interested in the relationship between the precision and accuracy of measurements will find this volume useful. Whether you are a physicist, a chemist, a social scientist, or a student studying one of these subjects, you will discover that the basis of measurement is the struggle to identify the needle of useful data hidden in the haystack of obscuring background noise.

Book Synopsis Measuring Compliance by : Melissa Rorie

Download or read book Measuring Compliance written by Melissa Rorie. This book was released on 2022-02-24. Available in PDF, EPUB and Kindle. Book excerpt: Compliance, or the behavioral response to legal rules, has become an important topic for academics and practitioners. A large body of work exists that describes different influences on business compliance, but a fundamental challenge remains: how to measure compliance or noncompliance behavior itself? Without proper measurement, it's impossible to evaluate existing management and regulatory enforcement practices. Measuring Compliance provides the first comprehensive overview of different approaches that are or could be used to measure compliance by business organizations. The book addresses the strengths and weaknesses of various methods and offers both academics and practitioners guidance on which measures are best for different purposes. In addition to understanding the importance of measuring compliance and its potential negative effects in a variety of contexts, readers will learn how to collect data to answer different questions in the compliance domain, and how to offer suggestions for improving compliance measurement.
