Dependent Variable

Dependent variable - in research, this is the variable that is changed by the independent variable, most often this is the "outcome" of the study.

• Example, in the study by Cleland et al. (1), the independent variable is "thoracic manipulation," and the dependent variable is "lower trapezius muscle strength."
