8.2 Quasi-experimental and pre-experimental designs
Quasi-experimental designs do not use random assignment. Comparison groups are used in quasi-experiments. Matching is a way of improving the comparability of experimental and comparison groups. Quasi-experimental designs and pre-experimental designs are often used when experimental designs are impractical.
58 12.2 Pre-experimental and quasi-experimental design
When true experiments and quasi-experiments are not possible, researchers may turn to a pre-experimental design (Campbell & Stanley, 1963). [4] Pre-experimental designs are called such because they often happen before a true experiment is conducted. Researchers want to see if their interventions will have some effect on a small group of people ...
Quasi-Experimental Design
True experimental design Quasi-experimental design; Assignment to treatment: The researcher randomly assigns subjects to control and treatment groups.: Some other, non-random method is used to assign subjects to groups. Control over treatment: The researcher usually designs the treatment.: The researcher often does not have control over the treatment, but instead studies pre-existing groups ...
Experimental vs Quasi-Experimental Design: Which to Choose?
What is a quasi-experimental design? A quasi-experimental design is a non-randomized study design used to evaluate the effect of an intervention. The intervention can be a training program, a policy change or a medical treatment. Unlike a true experiment, in a quasi-experimental study the choice of who gets the intervention and who doesn't is not randomized.
Experimental and quasi-experimental designs in implementation research
Quasi-experimental designs include pre-post designs with a non-equivalent control group, interrupted time series (ITS), and stepped wedge designs. Stepped wedges are studies in which all participants receive the intervention, but in a staggered fashion. It is important to note that quasi-experimental designs are not unique to implementation ...

Because of this, it is rare to see pre-experiments in academic journals.
