Discuss the three general types of experimental designs.

What will be an ideal response?


? Experimental designs (sometimes called true experimental designs) are characterized by random assignment to treatment and control groups and include the classical, posttest-only control group, and Solomon four-group designs.
? Quasi-experimental designs do not use random assignment of groups and instead employ matching or other means of obtaining equivalence of groups. Quasi-experimental designs include time-series and counterbalanced designs.
? Pre-experimental designs lack any equivalence of groups and include one- and two-group ex post facto and one-group before–after designs.
