Per Study.com (2017), Experimental research is when a researcher can manipulate the predictor variable and subjects to identify a cause-and-effect relationship. This typically requires the research to be conducted in a lab, with one group being placed in an experimental group, or the ones being manipulated, while the other is placed in a placebo group, or inert condition or non-manipulated group. A laboratory-based experiment gives a high level of control and reliability.
Per Study.com (2017), Non-experimental research is the label given to a study when a researcher cannot control, manipulate or alter the predictor variable or subjects, but instead, relies on interpretation, observation or interactions to conclude. Typically, this means the non-experimental researcher must rely on correlations, surveys or case studies, and cannot demonstrate a true cause-and-effect relationship. Non-experimental research tends to have a high level of external validity, meaning it can be generalized to a larger population.
The four most commonly used designs for research studies are descriptive, correlational, quasi- experimental, and experimental.”(Grove, Gray & Burns, 2015). Descriptive and correlational designs can be referred to as non-experimental designs because the focus is on examining variables as they naturally occur in environments and not in the implementing of a treatment by the researcher. In experimental design researchers uses random assignment and they manipulate an independent variable around a controlled variable. A true experimental design there must be randomizing, a control group and manipulator of a variable when examining the direct cause or predicted relationships between variables. In a quasi-experiment one of these aspects is missing, typically the random assignment of subjects to groups. (Sousa, Driessnack & Mendes, 2007).
