Straightforward Statistics de Chieh-Chen Bowen

Straightforward Statistics

Autor Chieh-Chen Bowen
en Limba Engleză Paperback – 25 noi 2015
The overall structure of the book is designed to have the reader look at the "big picture" so that the basic statistical concepts connect in a coherent and logical manner. Key terms are defined as they appear and the reader is engaged with diverse examples throughout.   Throughout the book the reader is reminded what they need to be able to recall with "You Must Remember This" boxes.   A rich source of practical resources are located at the end of chapters beginning with “What You learned" so that you have a summary of what you covered in a given chapter.  This is followed by Exercise Problems and Solutions to those problems as well as a "Learning Assessment" that includes multiple choice questions and "Free Response" questions with all the answers included in the back of the book.  A very complete and practical introduction to statistics with a goal of success for the student.

Recenzii

“This book does an admirable job of presenting the rationale for the formulas, which should help the student understand the material more deeply. Additionally, the examples used by the author do a nice job of helping students walk through the process of applying the formulas to address research hypotheses.”
“I have been impressed with the author’s ability to explain statistical constructs in a straightforward manner.”
