Experimental Research
Experimental research is research that relies on experimental methods to prove, disprove, verify, refute, or establish the validity of a process or procedure. It is an empirical investigation that relies on empirical methods to measure the facts and variables that are used. For instance, an experiment to establish the existence of gravity would measure variations in weight of items dropped, the distance from the ground that they were dropped from, and wind speed among other variables to determine that gravity exists and how much weight and distance affects the items dropping to the ground.
