Independent and Dependent Variable Practice

Front

What is an independent variable?

Back

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

What is a dependent variable?

Back

A dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

In the context of an experiment, how do you identify the independent variable?

Back

The independent variable is usually the one that you can manipulate or change, and it is often plotted on the x-axis of a graph.

In the context of an experiment, how do you identify the dependent variable?

Back

The dependent variable is what you measure in the experiment, and it is often plotted on the y-axis of a graph.

Example of independent and dependent variables: The time it takes to complete a puzzle depends on the number of puzzle pieces. Identify them.

Back

Independent: Puzzle Pieces; Dependent: Time.

Example of independent and dependent variables: A car's speed is determined by the amount of time it travels. Identify them.

Back

Independent: Time; Dependent: Speed.

Front

Example of independent and dependent variables: The volume of a gas in a container depends on the pressure applied. Identify them.

Back

Independent: Pressure; Dependent: Volume.

Front

What is the relationship between independent and dependent variables in an experiment?

Back

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