In experimental research an iv refers to the independent variable, and a dv refers to the dependent variable
In psychology, the independent variable (IV) is a feature of an experiment that is altered or adjusted by researchers rather than other experimental factors. Studying, for instance, would be the independent variable in an experiment looking at how studying affects test scores. Researches are attempting to ascertain whether variations in the independent variable (studying) cause appreciable variations in the dependent variable.
Dependent variable anticipated impact of the independent variable and is an anticipated alteration as a result of the experiment. It is not subject to manipulation by researchers; changes originate from the independent variable.
