What is the primary difference between true experiments and quasi-experimental designs? Why is this difference so important?
What will be an ideal response?
True experiment—experiment in which subjects are assigned randomly to an
experimental group that receives a treatment or other manipulation of the independent
variable and a comparison group that does not receive the treatment or receives some
other manipulation; quasi-experimental design—a research design in which there is a
comparison group that is comparable to the experimental group in critical ways, but
subjects are not randomly assigned to the comparison and experimental groups;
Researchers cannot be certain that they can rule out non-spurious relationships in a quasi-
experimental design since randomization of participants helps control this. Therefore,
causality may be affected.
