In some research, the researchers are not able to use random assignments to divide participants among groups. Instead, they compare preexisting groups, which results in a quasi-experimental design.
Random assignments are those which are given as a matter of chance to ensure fairness and equal opportunity for all participants. Here participants forming multiple groups are with similar characteristics. So all groups are the same at the start of the experiment.
A quasi-experimental design applies a non-random method, and subjects are assigned to preexisting groups. There are some situations where true experiments can't be used for practical reasons. In such cases, a quasi-experimental design is a suitable tool.
