Experimental research is a study that strictly adheres to a scientific research design. It includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated and compared. Most importantly, experimental research is completed in a controlled environment.
Experimental research, also called experimentation, is research conducted using a scientific approach using two or more variables. The first variable is a constant that you can manipulate to see the differences caused in the second variable. Most studies under quantitative research methods are experimental in nature.Mar 5, 2021
