QUASI-EXPERIMENTAL DESIGNS

QUASI-EXPERIMENTAL DESIGNS are usually constructions that already exist in the real world. Those designs that fall into the quasi-experimental category fall short in some way of the criteria for the true experimental group. A quasi-experimental design will have some sort of control and experimental group, but these groups probably weren't randomly selected. Random selection is usally where true-experimental and quasi-experimental designs differ.

Some advantages of the quasi-experimental design include:
