Successful in the first edition for its integration of multiple regression with evaluation design and for its systematic ways to select the proper goals for single and multiple outcome evaluations, this new edition is more helpful than ever. Impact Analysis for Program Evaluation, Second Edition has been revised to cover new issues and to further clarify the concepts used in impact analysis. It offers expanded coverage and explanation of quasiexperiments, a new section on the theory of impact analysis, updated information on the use of qualitative research for impact analysis, and expanded coverage of significance testing for program evaluation. It also includes an explanation of why the comparativechange design (i.e., Campbell and Stanley's 'nonequivalent control group' design) is better than an ex post facto design from the standpoint of causal inference.
⚠️ WARNING (California Proposition 65):
This product may contain chemicals known to the State of California to cause cancer,
