This text investigates the fundamental statistical methods and analytical tools essential for social work practitioners to evaluate research and inform evidence-based practice. The authors, Richard M. Grinnell Jr. and Robert W. Weinbach, leverage their extensive academic backgrounds in social work research to demystify complex quantitative concepts for students and professionals. By focusing on practical application rather than theoretical abstraction, the book provides a structured framework for interpreting data within the social services sector.

This text is regarded as a foundational resource for social work students, valued for its accessible approach to quantitative analysis. Its longevity across eight editions suggests a consistent utility in bridging the gap between statistical theory and the realities of social work practice.
