Making Sense of Data in the Media


Book Description

The amount of data produced, captured and transmitted through the media has never been greater. But for this data to be useful, it needs to be properly understood and claims made about or with data need to be properly scrutinized. Through a series of examples of statistics in the media, this book shows you how to critically assess the presentation of data in the media, to identify what is significant and to sort verifiable conclusions from misleading claims. How accurate are polls, and how should we know? How should league tables be read? Are numbers presented as ‘large’ really as big as they may seem at first glance? By answering these questions and more, readers will learn a number of statistical concepts central to many undergraduate social science statistics courses. By tying them in to real life examples, the importance and relevance of these concepts comes to life. As such, this book does more than teaches techniques needed for a statistics course; it teaches you life skills that we need to use every single day.

Making Sense of Data and Information


Book Description

Managers need to be able to make sense of data and to use it selectively to answer key questions: Why has quality fallen in the last week? Should we subcontract or employ more people? What will consumer demand be in the future? They need to be able to assess the value of data and to detect what is and what isn’t spin. The focus is on analysing numbers. On their own, figures tell us very little. To become meaningful they need to be processed and analysed and it is the patterns that emerge from this that provide the information that is needed for decision-making. The book is arranged in four themes. It starts by considering the value of information in organisations and by assessing how effectively the information is used in a management role. It then goes on to look at different options for presenting figures so that trends become clearer and patterns simpler to spot. As well as making data easier to interpret, the techniques the book presents are valuable communication tools that will help the reader use information more effectively with others. The last two themes then provide a toolkit of techniques that you can use to investigate situations and help solve problems. These include statistical and operational techniques as well as computer tools. Like any toolkit, the key to using it properly lies in knowing not only what each tool does but when to use it. This book will help the reader to develop this ability by applying the methods that are described within a business context.

Data Insights: New Ways to Visualize and Make Sense of Data offers thought-provoking insights into how visualization can foster a clearer and more comprehensive understanding of data. The book offers perspectives from people with different backgrounds, including data scientists, statisticians, painters, and writers. It argues that all data is useless, or misleading, if we do not know what it means.Organized into seven chapters, the book explores some of the ways that data visualization and other emerging approaches can make data meaningful and therefore useful. It also discusses some fundamental ideas and basic questions in the data lifecycle; the process of interactions between people, data, and displays that lead to better questions and more useful answers; and the fundamentals, origins, and purposes of the basic building blocks that are used in data visualization. The reader is introduced to tried and true approaches to understanding users in the context of user interface design, how communications can get distorted, and how data visualization is related to thinking machines. Finally, the book looks at the future of data visualization by assessing its strengths and weaknesses. Case studies from business analytics, healthcare, network monitoring, security, and games, among others, as well as illustrations, thought-provoking quotes, and real-world examples are included.This book will prove useful to computer professionals, technical marketing professionals, content strategists, Web and product designers, and researchers. - Demonstrates, with a variety of case studies, how visualizations can foster a clearer and more comprehensive understanding of data - Answers the question, "How can data visualization help me?" with discussions of how it fits into a wide array of purposes and situations - Makes the case that data visualization is not just about technology; it also involves a deeply human process




Information, Systems and Information Systems


Book Description

Information, Systems and Information Systems making sense of the field Peter Checkland and Sue Holwell Lancaster University, UK Science-based technology helps to shape our lives, and no technology is more powerful in this respect than that associated with information. But the emerging linked fields of information systems and information technology are still in a very confused state. There is a torrent of technical developments but the concepts which bring structure to the field and make sense of it lag behind. This book seeks to dispel that confusion, and aims to make sense of IS and IT as a whole. Conventional theory bears little relation to the experience most people have with computer-based systems in organizations. Based on real-world experiences in both the private and public sectors, this book from Peter Checkland and Sue Holwell tackles the subject afresh. Information, Systems and Information Systems provides a practice-based approach to the thinking needed to underpin provision of information support in organizations. Starting from fundamentals, the book develops a coherent account of the field. The book is thus a work of conceptual cleansing. It presents a well-argued and tested account of IS and IT which is both holistic and coherent. The sense-making models which emerge can encompass any particular assumptions about the nature of organizational reality and management, whether 'hard' functionalist or 'soft' interpretive ones, though the authors' sympathies are with the latter.
