Abstract

Experimental controls are techniques that researchers utilize to minimize the effects of extraneous experience and environmental variables as well as to strengthen the inference that changes in the dependent variable are due to the independent variable (the ability to infer causality). Does, for example, Treatment X (independent variable) cause a change in Behavior A (dependent variable)? A well-designed, well-controlled, and well-implemented randomized experiment is the best avenue for examining causality.
