Document Summary

Quasi-experimental design: have several of the key features of randomized experimental designs such as pre- post measurement & treatment control group comparisons by lack random assignment to a treatment group. Two types to be focused on are nonequivalent groups design (negd) and the regression-discontinuity design. Probably the most frequently used design in social research b/c its very intuitively sensible. Has a pre-post measure: measure treatment group before and after treatment is given. Has a control group that doesn"t get the treatment. Major challenge stems from the term nonequivalent, if your comparison group is really similar to the program group in all respects (except for receiving the program) this is a good design. Structured like a pretest-posttest randomized experiment, but lacks random assignment. Most often use the intact groups that you think are similar to the control and treatment groups. B/c its often likely the groups aren"t equivalent = why its called nonequivalent.
