Experimental vs. Non-Experimental Research
Provide an example of experimental, quasi-experimental, and nonexperimental research from the GCU Library and explain how each research type differs from the others. Evaluate the effectiveness of the research design of the study for two of the examples provided.
Experimental, quasi-experimental, and non-experimental research designs are fundamental methodologies in scientific studies, each differing in the level of control and manipulation exerted by the researcher.
1. Experimental Research:
This design involves the random assignment of participants to different groups, such as treatment and control groups, allowing for the manipulation of an independent variable to observe its effect on a dependent variable. The randomization process ensures that any observed effects can be attributed to the intervention, minimizing biases.
Example: A randomized controlled trial (RCT) assessing the efficacy of a new medication for hypertension, where participants are randomly assigned to receive either the medication or a placebo, and blood pressure changes are monitored over time…
