内容説明
Traditional statistical inference is integrated with the more modern idea of data analysis in this introductory text for non-technical students. Material begins with simple data sets and proceeds to those with more structure. Examples are plentiful and have been chosen from diverse fields, making the subject accessible to students of any academic field. The book contains many pictures as well as detailed calculations with step-by-step instructions and a formula to indicate in mathematical notation exactly what is being done. At the end of each chapter is a brief summary which reviews the material and explains key terms. Following this are questions which help readers review main new concepts and ideas, and practice problems (many with real data sets).
