内容説明 This third edition continues in the tradition of the broadly-used system first developed by the authors but with many modifications to reflect modern and developing practices in the field. It includes an increased emphasis on graphical presentations used throughout the text and new chapters have also been included， discussing such topics as alternative procedures， the potential problems of outliners， multilevel models for clustered data， and answering research questions using longitudinal data. While the book is addressed to behavioural and social scientists， it is also intended for a wide audience of students and researchers. The non-mathematical， applied， and data-analytic orientation of the book ensures the authors’ goal that anyone with an introductory knowledge of statistics can use it.
