✏Experimental and Quasi Experimental Designs for Research Book Summary : We shall examine the validity of 16 experimental designs against 12 common threats to valid inference. By experiment we refer to that portion of research in which variables are manipulated and their effects upon other variables observed. It is well to distinguish the particular role of this chapter. It is not a chapter on experimental design in the Fisher (1925, 1935) tradition, in which an experimenter having complete mastery can schedule treatments and measurements for optimal statistical efficiency, with complexity of design emerging only from that goal of efficiency. Insofar as the designs discussed in the present chapter become complex, it is because of the intransigency of the environment: because, that is, of the experimenter’s lack of complete control.

✏Experimental and Quasi experimental Designs for Generalized Causal Inference Book 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. The book covers four major topics in field experimentation: Theoretical matters: Experimentation, causation, and validity Quasi-experimental design: Regression discontinuity designs, interrupted time series designs, quasi-experimental designs that use both pretests and control groups, and other designs Randomized experiments: Logic and design issues, and practical problems involving ethics, recruitment, assignment, treatment implementation, and attrition Generalized causal inference: A grounded theory of generalized causal inference, along with methods for implementing that theory in single and multiple studies

✏Quasi Experimental Research Designs Book Summary : This pocket guide describes the logic, design, and conduct of the range of such designs, encompassing pre-experiments, quasi-experiments making use of a control or comparison group, and time-series designs. While it can be utilized as a manual, this book is also valuable for practitioners seeking a greater conceptual understanding of quasi-experimental studies in social work literature. Human service professionals planning to undertake a program evaluation of their agency's services will find this book helpful in understanding the steps and actions needed to adopt a quasi-experimental strategy.

✏Using Propensity Scores in Quasi Experimental Designs Book Summary : Using Propensity Scores in Quasi-Experimental Designs, by William M. Holmes, examines how propensity scores can be used to reduce bias with different kinds of quasi-experimental designs and to fix or improve broken experiments. Requiring minimal use of matrix and vector algebra, the book covers the causal assumptions of propensity score estimates and their many uses, linking these uses with analysis appropriate for different designs. Thorough coverage of bias assessment, propensity score estimation, and estimate improvement is provided, along with graphical and statistical methods for this process. Applications are included for analysis of variance and covariance, maximum likelihood and logistic regression, two-stage least squares, generalized linear regression, and general estimation equations. The examples use public data sets that have policy and programmatic relevance across a variety of disciplines.

✏Graphical Models for Quasi Experimental Designs Book Summary : Experimental and quasi-experimental designs play a central role in estimating cause-effect relationships in education, psychology, and many other fields of the social and behavioral sciences. This paper presents and discusses the causal graphs of experimental and quasi-experimental designs. For quasi-experimental designs the authors demonstrate that a causal treatment effect can be identified if they can isolate a subpopulation whose graph resembles the graph of an randomized controlled trial (RCT). For regression discontinuity (RD) designs, the corresponding subpopulation is given by the population in the very close neighborhood around the cutoff score; for the instrumental variable (IV) design, it is the subpopulation of compliers; for matching designs, it is the matched population and for propensity stratification (PS); for weighting designs it is the stratified or weighted population. The causal graphs also show that the identification of causal effects rests on stronger assumptions as the researchers' control over the study diminishes. More control usually implies the simpler data-generating mechanism and, thus, relative ease of identification. Figures are provided in the appendix.

✏Methodology and Epistemology for Social Sciences Book Summary : Since the 1950s, Donald T. Campbell has been one of the most influential contributors to the methodology of the social sciences. A distinguished psychologist, he has published scores of widely cited journal articles, and two awards, in social psychology and in public policy, have been named in his honor. This book is the first to collect his most significant papers, and it demonstrates the breadth and originality of his work.
