Without question, statistics is one of the most challenging courses for students in the social and behavioral sciences. Enrolling in their first statistics course, students are often apprehensive or extremely anxious toward the subject matter. And while IBM SPSS® is one of the more easy-to-use statistical software programs available, for anxious students who realize they not only have to learn statistics but also new software, the task can seem insurmountable. Keenly aware of students’ anxiety with statistics (and the fact that this anxiety can affect performance), Ronald D. Yockey has written SPSS® Demystified: A Simple Guide and Reference, now in its fourth edition. Through a comprehensive, step-by-step approach, this text is consistently and specifically designed to both alleviate anxiety toward the subject matter and build a successful experience analyzing data in SPSS®. Topics covered in the text are appropriate for most introductory and intermediate statistics and research methods courses.

Key features of the text:

• Step-by-step instruction and screenshots

• Designed to be hands-on with the user performing the analyses alongside the text on their computer as they read through each chapter

• Call-out boxes provided, highlighting important information as appropriate

• SPSS® output explained, with written results provided using the popular, widely recognized APA format

• End-of-chapter exercises included, allowing for additional practice

• SPSS® data sets available on the publisher’s website

New to the Fourth Edition:

• Fully updated to SPSS® 28

• Updated screenshots in full color to reflect changes in the SPSS® software system (version 28)

• Exercises updated with up-to-date examples

• Exact p-values provided (consistent with APA recommendations)
