Experimental Group: The group in a research study that receives the experimental drug, treatment, or procedure (Helbig, 2018).
Experimental [Randomized] Research Design: A type of quantitative research design that is highly controlled to study cause and effect with independent and dependent variables (Helbig, 2018).
Quasi-Experimental Research Design: A type of quantitative research design that is partially controlled that studies cause and effect of variables (Helbig, 2018). No randomization.
Nonexperimental Research: A research study that does not involve an experimental drug, treatment, or procedure (Helbig, 2018). Quantitative or qualitative.
The differences between each can be seen in the definitions but an experimental research design is quantitative that is highly controlled study where the dependent and independent variables matter, quasi-experimental is also quantitative but is only partially controlled with no randomization, and last, nonexperimental it is research that does not involve experimental drugs, treatments or procedures; it can be qualitative or quantitative.
