What are dependent variables in an experiment?

• Variables that are manipulated by the researcher and are expected to change as a result of the dependent variable.

• Variables that are not measured or observed and are not expected to change as a result of manipulating the independent variable.

• Variables that are measured or observed and are expected to change as a result of manipulating the independent variable.

• Variables that are not affected by the independent variable and do not change in an experiment.
