Independent/Dependent Variables and Graphing

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.

Front

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 a scientific experiment, what is the purpose of constants?

Back

Constants are the factors that remain the same throughout an experiment to ensure that the results are valid and reliable.

Front

What does the x-axis represent in a graph?

Back

The x-axis typically represents the independent variable in a graph.

Front

What does the y-axis represent in a graph?

Back

The y-axis typically represents the dependent variable in a graph.

Front

How do you identify the dependent variable in a question?

Back

The dependent variable is usually the outcome or effect that is being measured in response to changes in the independent variable.

Front

What is the relationship between independent and dependent variables?

Back

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

Front

Give an example of an independent variable in a plant growth experiment.

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 the effect of fertilizer on plant growth.

Back

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

Front

What is the role of a control group in an experiment?

Back

The control group is used as a standard for comparison and does not receive the experimental treatment.
