What is an independent variable?

Back

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

What is a dependent variable?

Back

A dependent variable is the variable that is measured and affected in an experiment, responding to changes in the independent variable.

How do you identify the dependent variable in a graph?

Back

The dependent variable is usually plotted on the y-axis and is the outcome that changes in response to the independent variable.

Front

How do you identify the independent variable in a graph?

Back

The independent variable is usually plotted on the x-axis and is the variable that is manipulated.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe how it affects the dependent variable.
