Editorial Reviews
Assuming no previous knowledge of statistics, introduces quantitative research technique, and shows how to plan a research project from formulation of a question through data collection, presentation, and evaluation. New to this third edition are research-related discussions on topics such as theory formation and ethics, and general introductions for sections on the scientific method, research designs, descriptive statistics, and inferential statistics. Includes self quizzes, questions and answers, and a glossary. Annotation c. Book News, Inc., Portland, OR (
From the Publisher
As a second year student with a research proposal looming, this book will prove extremely useful. The chapters are laid out in a logical and easy to follow way, and explanations of key areas are easily understandable.
The self assessment sections allow the student to track their progress and check their understanding. Overall, I would recommend this book to any student, like myself, who finds the thought of research methods frightening!!!!

- Laura Culpan, Physiotherapy Student, University of Bradford, UK.

As a first year Physio student I’ve not yet embarked on a research project. I have, however, found this book extremely useful to assist in the critical evaluation of research papers as it discusses all aspects from sampling to statistical analysis, including advantages and disadvantages of different methods.

I have also found the section on statistics extremely useful as I was finding it difficult understanding results and their statistical significance in papers as it’s not something I’ve previously been taught.

I feel that this book will be invaluable to me throughout and after my degree when I will be involved at research projects at various levels.
