A variable that is manipulated is known as:
Independent variable
To determine which variable is manipulated, we need to understand the definitions and roles of different types of variables involved in research or experiments:
- Control variable: This variable remains constant throughout the experiment to not affect the outcome. It is used to ensure that the effect of the independent variable is isolated.
- Dependent variable: This variable is observed and measured to evaluate the effect of changes made to the independent variable. It is the outcome or response that is hypothesized to be affected by variations in the independent variable.
- Independent variable: This variable is deliberately manipulated or changed by the researcher to observe how it affects the dependent variable. It is the presumed cause in the cause-and-effect relationship tested in an experiment.
- Confounding variable: An external variable that may affect the relationship between the independent and dependent variables by providing an alternative explanation for an observed effect.
Based on these definitions, the correct answer is the independent variable. This variable is manipulated by the experimenter to study its effects on the dependent variable. The independent variable is also often referred to as the "input variable" or the "predictor variable" in research studies.
Therefore, the variable that is manipulated is known as the Independent variable.
