Examples of Experimental Research The goal of experimental research is to answer a research question. To answer this question using a fundamental research design, researchers randomly assign participants to at least two different groups: an experimental and a control group. Participants are tested before...
Quasi-experimental research is a design that closely resembles experimental research but is different. The term “quasi” means “resembling,” so you can think of it as a cousin to actual experiments. In these studies, researchers can manipulate an independent variable — that is, they change o...
Quasi-experimental research designs are the most widely used research approach employed to evaluate the outcomes of social work programs and policies. This new volume describes the logic, design, and conduct of the range of such designs, encompassing pre-experiments, quasi-experiments making use of ...
Remember also that using one type of design does not preclude using the other type in a different study. There is no reason that a researcher could not use both a between-subjects design and a within-subjects design to answer the same research question. In fact, professional researchers often...

This text introduces and provides instruction on the design and analysis of experiments for a broad audience. Formed by decades of teaching, consulting, andindustrial experience in theDesign of Experiments field, this new edition contains updated examples, exercises, and situations covering the science...
We provide both an introduction to the principles of experimental design and examples of influential applications of design for different types of social science research. Our aim is twofold: to provide a foundation in the principles of design that may be useful to those planning experiments and ...
Questionable Research Practices in Single-Case Experimental Designs: Examples and Possible Solutionsdoi:10.1007/978-3-031-04968-2_12Questionable research practices (QRPs) are a variety of research choices that introduce bias into the body of scientific literature. Researchers have documented widespread ...
This book presents a comprehensive overview of the theory and practice of experimental research in the field of social work. Bruce A. Thyer illustrates key principles through examples of how social workers have evaluated real-world practice approaches.
