experimental study might be a more cost-effective design, because such a design would allow for conclusions to be drawn about whether the program causes changes in outcomes for participants. CONCLUSION Many types of quasi-experimental designs are possible. They vary widely in cost and difficulty. When a

the study is either experimental or quasi-experimental. If not, the study will fit into one of the other categories. If you see the word “association” in the title, the study is likely to be a descriptive, epidemiological, or predictive correlation design. experimental study designs Quasi-Experimental Designs: Definition, Characteristics ... This lesson explores the basic definition of why there is the label of quasi-experimental design in addition to what types of designs are quasi-experimental. QUASI-EXPERIMENTAL D Types Of Quasi-Experimental Designs 1. Nonequivalent Control Group Designs—research designs having both experimental and control groups but the participants are NOT randomly assigned to these groups. • This is the most common type of quasi-experimental design. • Problems with this type of design have to do with how to compare the results QUANTITATIVE RESEARCH DESIGNS: EXPERIMENTAL all types. A quasi-experimental design involves the use of an intervention, but not random assignment of participants to groups. A factorial design also involves two or more groups, but the researcher tests for the interaction of two or more independent variables.
