Dependent and Independent Variable Review

Front

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.

Front

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.

Front

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

How do you write an ordered pair?

Back

An ordered pair is written as (X, Y), where X is the independent variable and Y is the dependent variable.

Front

What does it mean if a variable is 'controlled'?

Back

A controlled variable is one that is kept constant throughout an experiment to ensure that the results are due to the independent variable.

Front

Give an example of an independent variable in a study about plant growth.

Back

An example of an independent variable could be the amount of sunlight the plants receive.

Front

Give an example of a dependent variable in a study about plant growth.

Back

An example of a dependent variable could be the height of the plants after a certain period.

Front

What is the purpose of a graph in scientific experiments?

Back

A graph visually represents data, making it easier to identify trends, relationships, and patterns between variables.

Front

What is the relationship between independent and dependent variables?

Back

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