Book Description: This acclaimed statistics text requires no prior knowledge of statistics, emphasizing a conceptual understanding of the topic and its usefulness to social work practice and research. Rather than focusing on mathematical computation, Statistics for Social Workers instead focuses on providing an understanding of the logical underpinnings of statistical analysis and how to apply the results of analysis in a social work practice environment. The authors have used this approach to teaching statistics for over 25 years, and it remains the most widely used book of its kind. Highlights of the Sixth Edition: Includes new discussion of why random samples often cannot be used in social work research and how this affects the choice of tests that are appropriate for use. New appendix covers statistical analysis of program evaluation data and single system research data, linking research and practice. Includes expanded content on how design flaws such as measurement error, measurement bias, and cultural bias can produce spurious relationships between variables. New case examples further clarify how various statistical tests can be used in practice and research and how their results can be interpreted.
