RESEARCH METHODOLOGY Methods and tools use in research

experimental research is lacking (i.e. manipulation, randomization, and control group). There are too many types of Quasi-experimental design to go into in great depth. Most are adaptations of experimental designs where one of the three elements is missing. Randomization : The experimenter assigns participants to different groups on a random ...

Quasi-Experimental Design and Methods - unicef-irc.org

Quasi-experimental research designs, like experimental designs, test causal hypotheses. A quasi-experimental design by definition lacks random assignment. Quasi-experimental designs identify a comparison group that is as similar as possible to the treatment group in terms of baseline (pre-intervention) characteristics.

Experimental Research Designs

ing the experimental design is difficult or impossible, premature, or unethical. For this reason, there are a variety of what are called quasi-experimental designs, as well as descriptive and observational designs. The experimental and quasi-experimental designs, along with their strengths and drawbacks, are discussed in this chapter.
