How can you identify the independent variable in a given scenario?

The independent variable can be identified as the factor that is changed or controlled in an experiment.

Front

How can you identify the dependent variable in a given scenario?

Back

The dependent variable can be identified as the factor that is measured or observed in response to changes in the independent variable.

The height of the plants after a certain period.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

What is the purpose of a control variable in an experiment?

Back

A control variable is kept constant to ensure that any changes in the dependent variable are due to the manipulation of the independent variable.
