Download or read book Learning to See Data written by Ben Jones and published by Data Literacy Press. This book was released on 2020-12-15 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is associated with the 'Data Literacy Level 1' on-demand online course: https://dataliteracy.com/courses/data-literacy-level-1 For most of us, it's rare to go a full day without coming across data in the form of a chart, map or dashboard. Graphical displays of data are all around us, from performance indicators at work to election trackers on the news to traffic maps on the road. But few of us have received training or instruction in how to actually read and interpret them. How many times have we been misled simply because we aren't aware of the pitfalls to avoid when interpreting data visualizations. Learning to See Data will teach you the different ways that data can be encoded in graphical form, and it will give you a deeper understanding of the way our human visual system interprets these encodings. You will also learn about the most common chart types, and the situations in which they are most appropriate. From basic bar charts to overused pie charts to helpful maps and many more, a wide array of chart types are covered in detail, and conventions, pitfalls, strengths and weaknesses of each of them are revealed. This book will help you develop fluency in the interpretation of charts, an ability that we all need to hone and perfect if we are to make meaningful contributions in the professional, public and personal arenas of life. The principles covered in it also serve as a critical background for anyone looking to create charts that others will be able to understand. "This book is clear and evocative, thorough and thoughtful, and remarkably readable: a marvelous launchpad into the world of data." –Tamara Munzner, Professor, University of British Columbia Computer Science "Everyone of us needs good data literacy skills to survive in the modern world. Without them, it's hard to succeed at work, or survive the onslaught of information (and misinformation) across all our media. Ben's book provides the necessary building blocks for a strong foundation. From that foundation, Ben's approach will inspire you to own the process of developing your skills further." –Andy Cotgreave, Technical Evangelism Director, Tableau

Download or read book Common System and Software Testing Pitfalls written by Donald G. Firesmith and published by Addison-Wesley Professional. This book was released on 2014-01-17 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Don’s book is a very good addition both to the testing literature and to the literature on quality assurance and software engineering... . [It] is likely to become a standard for test training as well as a good reference for professional testers and developers. I would also recommend this book as background material for negotiating outsourced software contracts. I often work as an expert witness in litigation for software with very poor quality, and this book might well reduce or eliminate these lawsuits....” –Capers Jones, VP and CTO, Namcook Analytics LLC Software and system testers repeatedly fall victim to the same pitfalls. Think of them as “anti-patterns”: mistakes that make testing far less effective and efficient than it ought to be. In Common System and Software Testing Pitfalls, Donald G. Firesmith catalogs 92 of these pitfalls. Drawing on his 35 years of software and system engineering experience, Firesmith shows testers and technical managers and other stakeholders how to avoid falling into these pitfalls, recognize when they have already fallen in, and escape while minimizing their negative consequences. Firesmith writes for testing professionals and other stakeholders involved in large or medium-sized projects. His anti-patterns and solutions address both “pure software” applications and “software-reliant systems,” encompassing heterogeneous subsystems, hardware, software, data, facilities, material, and personnel. For each pitfall, he identifies its applicability, characteristic symptoms, potential negative consequences and causes, and offers specific actionable recommendations for avoiding it or limiting its consequences. This guide will help you Pinpoint testing processes that need improvement–before, during, and after the project Improve shared understanding and collaboration among all project participants Develop, review, and optimize future project testing programs Make your test documentation far more useful Identify testing risks and appropriate risk-mitigation strategies Categorize testing problems for metrics collection, analysis, and reporting Train new testers, QA specialists, and other project stakeholders With 92 common testing pitfalls organized into 14 categories, this taxonomy of testing pitfalls should be relatively complete. However, in spite of its comprehensiveness, it is also quite likely that additional pitfalls and even missing categories of pitfalls will be identified over time as testers read this book and compare it to their personal experiences. As an enhancement to the print edition, the author has provided the following location on the web where readers can find major additions and modifications to this taxonomy of pitfalls: http://donald.firesmith.net/home/common-testing-pitfalls Please send any recommended changes and additions to dgf (at) sei (dot) cmu (dot) edu, and the author will consider them for publication both on the website and in future editions of this book.

Download or read book Measurement Madness written by Dina Gray and published by John Wiley & Sons. This book was released on 2015-01-27 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: A clearer, more accurate performance management strategy Over the past two decades, performance measurement has profoundly changed societies, organizations and the way we live and work. We can now access incredible quantities of data, display, review and report complex information in real time, and monitor employees and processes in detail. But have all these investments in collecting, analysing and reporting data helped companies, governments and people perform better? Measurement Madness is an engaging read, full of anecdotes so peculiar you'll hardly believe them. Each one highlights a performance measurement initiative that went wrong, explains why and – most importantly – shows you how to avoid making the same mistake yourself. The dangers of poorly designed performance measurement are numerous, and even the best how-to guides don't explain how to avoid them. Measurement Madness fills in the gap, showing how to ensure you’re measuring the right things, rewarding the behaviours that deserve rewarding, and interpreting results in a way that will improve things rather than complicate them. This book will help you to recognize, correct and even avoid common performance measurement problems, including: Measuring for the sake of measuring Assuming that measurement is an instant fix for performance issues Comparing sets of data that have nothing in common and hoping to learn something Using targets and rewards to promote certain behaviours, and achieving exactly the opposite ones. Reading Measurement Madness will enable you to design a simple, effective performance measurement system, which will have the intended result of creating value in your organization.

Available in PDF, EPUB and Kindle. Book excerpt: Nothing masks issues and robs an organization of its full potential like success That's right! Most successful, growth-hungry companies begin to miss their projections or worse, not because demand is low or conditions are difficult, but simply because they don't know how to predict, nurture, or even maintain their own growth and success.

Dando, known in leadership circles as the "Company Whisperer," has encountered every one of these obstacles himself, as a C-level executive in a high-growth billion-dollar business. He knows firsthand that these moments of truth determine whether you can lead your company to become a strong, mature, and financially sustainable organization, or drift toward an uncertain future.

Download or read book Making Marriage Work written by Rob Pascale and published by Rowman & Littlefield. This book was released on 2016-02-23 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Staying happily married has become a difficult proposition in recent times. Although the institution is still firmly embedded in our culture, divorce rates have steadily climbed since the 1960s. While some marriages are truly divorce-worthy, many other broken marriages can be saved. Recent emphasis on personal needs and greater social acceptance of divorce and alternative lifestyles may have weakened the resolve of partners to work through their problems. Furthermore, many couples may not realize that problems in their current marriages are likely to surface in other relationships. Consequently, while they may consider divorce a solution, it may in fact only be a stepping stone to the next relationship where patterns may repeat. Solving marital differences can be difficult. They tend to be linked to or caused by other problems, and that can make it hard to identify the real reasons for conflicts. Without knowing the true nature of their problems, couples cannot arrive at solutions that actually work. To understand the underlying issues that plague many marriages, the authors look to the research conducted on the subject over the past fifty years and to real life stories of success and failure to outline the major issues that detract from marital stability. Drawing on Louis Primavera’s twenty-five years in private practice as a marriage counselor, each chapter is peppered with anecdotes that every married person can relate to, and that help bring issues to life. The authors also propose frank and honest solutions that can help couples have more satisfying relationships. Anyone looking to improve their marriage will find suggestions for sussing out the underlying problems they may be experiencing and guidance for addressing those problems.
