The two major types of quasi-experimental designs are: (1) nonequivalent control group designs, which have experimental and comparison groups that are designated before the treatment occurs and are not created by random assignment; and (2) before-and-after designs, which have both a pre- and post-test but no comparison group (Schutt). Sets of hypotheses can likewise be constructed for the remaining independent and dependent variables in Table 1. it is very helpful and important to define the independent and dependent variables in your research, and this should be done at the beginning of any experiment.
