We discuss the nature of statistics (the science of learning from data), its history and traditions, what characterises statistical thinking and how it differs from mathematics, connections with computing and data science, why learning statistics is essential, and what is most important. Finally, we attempt to gaze into the future, drawing upon what is known about the fast-growing demand for statistical skills and the portents of where the discipline is heading, especially those arising from data science and the promises and problems of big data. Key Words Discipline of statistics; Statistical thinking; Value of statistics; Statistical fundamentals; Decision making; Trends in statistical practice; Data science; Computational thinking 1.1 Introduction In this, the opening chapter of the International Handbook of Research in Statistics Education, we ask the question, “What is statistics?” This question is not considered in isolation, however, but in the context of grounding research in statistics education. Educational endeavour in statistics can be divided very broadly into “What?” and “How?” The “What?” deals with the nature and extent of the discipline to be conveyed, whereas any consideration of “How?” (including “When?”) brings into play a host of additional factors, such as cognition and learning theories, audience and readiness, attitudes, social interactions with teachers and other students, and learning and assessment strategies and systems.
