Dependent and Independent Variable Review

Front

What is a dependent variable?

Back

A dependent variable is a variable that depends on or is changed by another variable in an experiment.

Front

What is an independent variable?

Back

An independent variable is a variable that is changed or controlled in an experiment to test its effects on the dependent variable.

On which axis is the independent variable plotted on a graph?

Back

The independent variable is plotted on the x-axis.

Front

On which axis is the dependent variable plotted on a graph?

Back

The dependent variable is plotted on the y-axis.

Front

If you change the amount of sunlight a plant receives, what type of variable is sunlight?

Back

Sunlight is the independent variable.

Front

If you measure the height of a plant after changing the sunlight, what type of variable is height?

Back

Height is the dependent variable.

Front

What does it mean to control variables in an experiment?

Back

Controlling variables means keeping all other variables constant except for the independent variable to ensure a fair test.

Front

What is the purpose of a graph in representing data?

Back

A graph visually represents data to show relationships between variables.
