# Introductory Statistics Using SPSS

- Herschel Knapp - University of Southern California, USA

**Second Edition**of Herschel Knapp’s friendly and practical introduction to statistics shows students how to properly select, process, and interpret statistics without heavy emphasis on theory, formula derivations, or abstract mathematical concepts. Each chapter is structured to answer questions that students most want answered:

*What statistical test should I use for this situation? How do I set up the data? How do I run the test? How do I interpret and document the results?*Online tutorial videos, examples, screenshots, and intuitive illustrations help students "get the story" from their data as they learn by doing, completing practice exercises at the end of each chapter using prepared downloadable data sets.

**Available with Perusall—an eBook that makes it easier to prepare for class**

*Perusall*is an award-winning eBook platform featuring social annotation tools that allow students and instructors to collaboratively mark up and discuss their SAGE textbook. Backed by research and supported by technological innovations developed at Harvard University, this process of learning through collaborative annotation keeps your students engaged and makes teaching easier and more effective.

"This student-friendly text, coupled with an ample number of practice exercises and instructional videos for each chapter, provided my students with the resources to become proficient in using SPSS to perform and interpret the statistical analyses covered in the course. In addition, this text emphasizes and models the written communication of results and conclusions derived from research."

**Centenary University**

“I find the videos extremely helpful. Of particular note was the pre-test checklist. This list helps students to understand what criteria need to be met for the test to be used. The directions provided are incredibly detailed and provide ample guidance to students with limited computer skills….Overall, I found this book to be the best of those that I have used or reviewed.”

**Montclair State University**

“This is one of the best introductory SPSS texts on the market. It is easy to read, clear, concise and does not overwhelm the reader with abstract statistical theory. The exercises and examples are good and will be really useful both in class and for homework assignments. The online resources are a great addition and really help in understanding the material in the text.”

**College of Staten Island, City University of New York**

I highly recommend this book for everyone who wish to use SPSS. It is well written, easy to understand and to follow. The learning objectives at the beginning of the chapters give a good starting point.

**Childhood and Youth study, Univeristy of Chichester**

Finally a clear and concise book that presents with parametric and non-parametric equivalents together. I'm a fan!
