`With this book David de Vaus has written one of the best general
research methods textbooks around. The use of different types of
research design as the point of departure is a different and very
helpful approach to take, especially since many textbooks confuse issues
of method and design. The author outlines with great clarity a wide
variety of issues, including testing theories, causation, data analysis,
and the main considerations involved in using the different research
designs covered. Both students and their instructors will find this an
extremely valuable, well-written book′ - Alan Bryman, University of
