What is an independent variable?

Back

An independent variable is a variable that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

What does it mean if a variable is 'controlled' in an experiment?

Back

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

What is the purpose of identifying independent and dependent variables in an experiment?

Back

Identifying these variables helps to clarify the relationship being tested and ensures that the experiment is structured correctly.
