Types of Quasi-Experimental Design One of the most common types of quasi-experimental design is the nonequivalent group's design. In a true experiment, it is important to have equivalent control and experimental groups, as this helps to make results more comparable and statistically sound. ...
Quasi-experimental design attempts to establish a cause-and-effect relationship by using criteria other than randomization.

An ITS is a Quasi-Experimental Design that Can Be Used to Evaluate an Intervention when a True Randomised Controlled Experiment Is Not FeasibleAtle FretheimKari HåvelsrudGraeme MacLennanDoris Tove KristoffersenAndrew D Oxman
an experimental research design is a method in which at least two groups are used, one of which is a control group. A control group is a group that is not given any treatment during the experiment. Also, for a true experimental design, subjects are selected at random and, therefore, the...

Quasi-experimental design A quasi-experimental design is one that looks like an experimental design but lacks the key ingredient -- random assignment.

They ran a field experiment in a course at the University of Calabria (Italy) where students were given the opportunity to choose between two evaluation schemes at the beginning of a course: the traditional system or their experimental alternative. Students opting for the latter were randomly ...
