What are the characteristics of nonequivalent comparison-group quasi-experimental design and how are rival hypotheses that might explain the results?
What will be an ideal response?
Ans: In nonequivalent comparison-group quasi-experimental research designs, there is an experimental group and a comparison group, both of which are given pretest and posttest measures. Since there is no random assignment, researchers must rule out rival hypotheses. This is accomplished in many ways. One way is through the analysis of covariance where pretest scores are statistically removed from posttest scores. Matching can also help in ruling out rival hypotheses. Finally looking at the pattern of results can be used.
