What is a dependent variable?

Back

A dependent variable is an amount that depends on another amount, and it is measured in an experiment to see how it changes in response to the independent variable.

If the independent variable is time, what is the dependent variable in a distance-time graph?

Back

The dependent variable is distance.

Front

What does it mean if a variable is independent?

Back

It means that the variable can change freely and is not affected by other variables in the experiment.

Front

What does it mean if a variable is dependent?

Back

It means that the variable's value depends on the changes made to the independent variable.
