Statistics for Psychology is an interactive, highly visual, and accessible guide to the statistical practices you will encounter as a psychology student. Its software-agnostic approach keeps the focus on the core principles, rather than getting bogged down in complicated formulae and jargon. This book is based on the authors' BPS commended programme. It focusses on providing the strong foundational understanding you’ll need to use statistics confidently and creatively rather than the software-specific way in which statistics is often taught.

This edition includes:
  • new content throughout on being a responsible researcher,
  • a new chapter to support you in presenting your research to a critical audience,
  • carefully designed graphics to explain statistical principles,
  • “your turn” exercises to test your understanding of each chapter.

This book is the ideal guide for students approaching statistics and research methods in psychology for the first time. 

Roger Watt is Emeritus Professor of Psychology at the University of Stirling.
Elizabeth Collins is a researcher with a PhD in Psychology.

I liked the presentation of the book a lot. The book also covers well the basic of research methods from the statistical point of view. However, for my course's purposes, there was too much emphasis on the research methods (which will be covered on another course) and too little about the exact statistical analyses we will cover during the course.

A very good book that provides useful background information for any undergraduate psychology student.
