dependent variable
What gets measured
A dependent variable is what gets measured in an experiment—the outcome that changes in response to what the researcher manipulates.
In Does caffeine improve reaction time? , reaction time is the dependent variable because it depends on caffeine intake.
The term contrasts with independent variable, which is what the experimenter controls.
