Since the first edition came out in 1994, thousand of students in educational statistics courses and their professors have found it to be an excellent textbook. Educational practitioners have also appreciated keeping this book on their reference shelf. Now in its fourth edition, this well-regarded text is a clear and easy-to-follow manual for use in introductory statistics or action research courses. Ruth Ravid concentrates on the essential concepts in educational statistics including when to use various statistical tests and how to interpret the results. Testing and test score interpretation, reliability, and validity are included to help students understand these topics which are essential for practitioners in education. Real-life examples, used generously throughout, are taken from the field of education and presented to illustrate the various concepts and terms.

Editorial Reviews

Linda A. Catelli
Practical Statistics For Educators is a thoughtfully designed text that enables educators to easily understand and apply statistics and research in the field of education. I like the author’s style of writing, flow of information and the way she makes the application of statistics user-friendly! The book reduces course anxiety for anyone who may have a fear of statistics and provides users with a comfort level not found in many of other texts of its kind.
Philip A. Griswold
Concise but thorough treatment of elementary principles. I will use the text for a 2-course research method sequence for masters candidate.
Jan Seiter

To the reader who is a researcher, this is your text. To the administrator who needs a quick reference for understanding of statistical material, this is your text. To the doctoral candidate who’s writing a dissertation, this is your text. The author makes difficult material understandable…finally!
Michelle Ann Bakerson
A brilliant gem full of practical, hands-on information ripe for the educational researcher’s data driven decision needs, this book is the perfect balance of abstract theory and practical example intertwined always with the needs of educators in mind. I use this book in my educational research courses, with program evaluation for non-profits and highly recommend it to faculty teaching statistics or action research.
Daniel R. Tomal
