Aiming to provide the concepts and tools to analyze data intelligently, the early chapters in this work emphasize collection, display, examination, summary and presentation of data. Inference is reserved for later chapters when students should be familiar with data structures and data variability. The book: uses real data to motivate and explain methods and concepts; emphasizes statistical thinking rather than algebra or arithmetic; uses international examples; stresses graphical and numerical summaries of data before formal inference; and covers topics needed for the intelligent use of statistics in the computer age.
