Download and read online ebook Quantifying Measurement write by Jeffrey H Williams. This book was released on 2016-11-01. Quantifying Measurement available in PDF, EPUB and Kindle. 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.

Quantifying the User Experience: Practical Statistics for User Research, Second Edition, provides practitioners and researchers with the information they need to confidently quantify, qualify, and justify their data. The book presents a practical guide on how to use statistics to solve common quantitative problems that arise in user research. It addresses questions users face every day, including, Is the current product more usable than our competition? Can we be sure at least 70% of users can complete the task on their first attempt? How long will it take users to purchase products on the website? This book provides a foundation for statistical theories and the best practices needed to apply them. The authors draw on decades of statistical literature from human factors, industrial engineering, and psychology, as well as their own published research, providing both concrete solutions (Excel formulas and links to their own web-calculators), along with an engaging discussion on the statistical reasons why tests work and how to effectively communicate results. Throughout this new edition, users will find updates on standardized usability questionnaires, a new chapter on general linear modeling (correlation, regression, and analysis of variance), with updated examples and case studies throughout. Completely updated to provide practical guidance on solving usability testing problems with statistics for any project, including those using Six Sigma practices Includes new and revised information on standardized usability questionnaires Includes a completely new chapter introducing correlation, regression, and analysis of variance Shows practitioners which test to use, why they work, and best practices for application, along with easy-to-use Excel formulas and web-calculators for analyzing data Recommends ways for researchers and practitioners to communicate results to stakeholders in plain English

Download and read online ebook Measuring Social Change write by Alnoor Ebrahim. This book was released on 2019-07-16. Measuring Social Change available in PDF, EPUB and Kindle. The social sector is undergoing a major transformation. We are witnessing an explosion in efforts to deliver social change, a burgeoning impact investing industry, and an unprecedented intergenerational transfer of wealth. Yet we live in a world of rapidly rising inequality, where social sector services are unable to keep up with societal need, and governments are stretched beyond their means. Alnoor Ebrahim addresses one of the fundamental dilemmas facing leaders as they navigate this uncertain terrain: performance measurement. How can they track performance towards worthy goals such as reducing poverty, improving public health, or advancing human rights? What results can they reasonably measure and legitimately take credit for? This book tackles three core challenges of performance faced by social enterprises and nonprofit organizations alike: what to measure, what kinds of performance systems to build, and how to align multiple demands for accountability. It lays out four different types of strategies for managers to consider—niche, integrated, emergent, and ecosystem—and details the types of performance measurement and accountability systems best suited to each. Finally, this book examines the roles of funders such as impact investors, philanthropic foundations, and international aid agencies, laying out how they can best enable meaningful performance measurement.
