Summary: This long awaited successor of the original Cook/Campbell Quasi-Experimentation: Design and Analysis Issues for Field Settings represents updates in the field over the last two decades.This edition places a new emphasis on the generalization of causal connections and design elements rather than designs, with extensive attention given to methods for studying external validity. The authors pay specific attention to describing how testing casual propositions can be impr ...show moreoved in specific research projects and outline ways to improve generalizations about them through field experimentation.
Instead of focusing on the statistical analysis of data, the text considers these details in brief paragraphs or chapter appendices, using a conceptual focus and leaving most equations in footnotes. In addition, three chapters are devoted to the logic and design of randomized experiments, and the practical problems and solutions in their implementation.
