Nonexperimental and Quasi-Experimental Strategies — Nonequivalent Groups, Pre–Post Designs, and Developmental Methods | Chapter 10 of Research Methods for the Behavioral Sciences
Nonexperimental and Quasi-Experimental Strategies — Nonequivalent Groups, Pre–Post Designs, and Developmental Methods | Chapter 10 of Research Methods for the Behavioral Sciences Chapter 10 of Research Methods for the Behavioral Sciences introduces nonexperimental and quasi-experimental research strategies, which differ from true experiments in their lack of random assignment and limited control over variables. These approaches are frequently used in psychology when randomization is not feasible or ethical, and while they cannot establish definitive cause-and-effect relationships, they still provide valuable insights into behavioral phenomena.

Nonexperimental vs. Quasi-Experimental Strategies Both strategies lack the full control of true experiments, but they differ in degree: Nonexperimental designs: Do not attempt to control for internal validity threat...
