Experimental and Quasi-Experimental Research Research is imperative to quality analysis and development of theories. In any science, no matter if it is a physical, psychological, or sociological, research is integral to formulation of working theories. Without research, not only can problems not be solved but problems cannot even be properly determined. Having said that, it is important to understand that there are many different types of research methodology. Not all forms of research, and thus the data that they collect, are created equal. Some methods of research are far superior to others and the findings of researchers more influential and verifiable than research conducted in other methods. In The Research Methods Knowledge Base, authors Trochim and Donnelly (2008) discuss the importance of research and also explain the difference between types of research that can be conducted. Two types of research that they explore are experimental and quasi-experimental...

This is because that experimental research will be testable data which will be able to be repeated by subsequent researchers. Thus, the data that is received from the research will have the most internal validity. Experimental research ensures that the findings of analysts and researchers are most likely to be correct. Most experimental research is designed to find causations for given outcomes. To have true experimental research, it must be made evident that the causation that is determined by researchers is the only reason for what is witnessed. Experimental research also requires what Trochim & Donnelly call "random assignment," meaning that there cannot be any other…
