Quasi-experimental research designs lack what feature found in true experimental research?

Question

Quizplus · Accepted Answer

Quasi-experimental research designs lack randomization, which is a key feature of true experimental designs. In true experiments, participants are randomly assigned to either the treatment or the control group to ensure that the groups are equivalent at the start of the experiment. Quasi-experiments do not use this random assignment, which can lead to differences between groups that are not due to the treatment.
