Experimental, Quasi-Experimental, and Correlational Research Experimental, Quasi-Experimental, and Correlational Research Scientific research involves asking questions about a test subject and coming up with conclusion from the answers given. Considering the diversity in questions asked during a scientific research, there has been need to come up with standards procedure in doing research. These include quasi-experimental, experimental, and correlation research (Raulin and Graziano, 1993). However, these procedures differ in various ways. The difference is usually in the area each method focuses on. Experimental research generally focus on the impact one variable has over the other in an experiment, often, the effect of independent over dependent variable.

The independent variable is controlled by presenting it to a test group which is assumed to be equivalent at the beginning of the research. Quasi-experimental research, unlike experimental research, goes further and considers the fact that, it is not a must for all the groups involved in an experiment to be equivalent at the start of the study. According to Raulin and Graziano (1993), for credible result, it is important to conduct a pre-test on the subject before the test, so as, to have a rough idea on what to expect.

This will also help in ruling out or avoiding any contradicting variables that may rise during the experiment. In the case of correlation research, the key focus is usually on the bond between the variables themselves. It indicates the status of the variables, positive or negative, and the magnitude of the variables which may be strong or weak (Oswald et al, 2008). In conclusion, it is clear that experiment research focus on the questions about the variables, quasi-experiment on the differences among the test groups and finally, correlation focuses on the direction and strength of the variables.

Therefore, it is clear there are different research methods with different approaches. It is also clear that clarity in scientific research is well tested and all possible contradiction considered.
