However, unlike a true experiment, a quasi-experiment does not rely on random assignment. Instead, subjects are assigned to groups based on non-random criteria. Quasi-experimental research shares similarities with the traditional experimental design or randomized controlled trial, but it specifically lacks the element of random assignment to treatment or control.

It is important to note that quasi-experimental designs are not unique to implementation • Quasi experimental design is more suitable for real natural world setting than true experimental designs. • This design allows the researchers to evaluate the impact of quasi independent variables under naturally occurring conditions. • In some cases hypotheses are practically answered through this design. 17.

Quasi-experimental designs share a common weakness: the absence of randomization in selecting the participants, which does not ensure the comparability of the groups.

Probably the commonest way to design an experiment in psychology is to divide the participants into two groups, the experimental group, and the control group, and then introduce a change to the experimental group and not the control group.

The intervention can be a training program, a policy change or a … Quasi-experimental designs identify a comparison group that is as similar as possible to the intervention group in terms of baseline (pre-intervention) characteristics. The comparison group captures what would have been the outcomes if the programme/policy had not been implemented (i.e., the counterfactual). 2018-06-05 An experiment in which participants are assigned to either control groups or experimental groups in a non-random manner.
