AP PSYCHOLOGY

Detailed explanation-1: -The independent variable (IV) in psychology is the characteristic of an experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.

Detailed explanation-2: -Question: What’s an independent variable? Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure.

Detailed explanation-3: -An independent variable (IV) is a variable that is manipulated by a researcher to investigate whether it consequently brings change in another variable. This other variable, which is measured and predicted to be dependent upon the IV, is therefore named the dependent variable (DV).

Detailed explanation-4: -The dependent variable is the item that responds to the change of the independent variable. The dependent variable depends/changes when the independent variable is changed.

Detailed explanation-5: -The independent variable is “independent” because its variation does not depend on the variation of another variable in the experiment/research project. The independent variable is controlled or changed only by the researcher. This factor is often the research question/hypothesis behind the outcome of the experiment.
