independent and dependent variable

Front

What is the definition of a dependent variable?

Back

A dependent variable is a variable that changes in response to the independent variable. It is what is measured in an experiment.

What is the definition of an independent variable?

Back

An independent variable is a variable that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

On which axis of a graph is the dependent variable typically plotted?

Back

The dependent variable is typically plotted on the y-axis.

Front

On which axis of a graph is the independent variable typically plotted?

Back

The independent variable is typically plotted on the x-axis.

Front

In the context of a restaurant meal, if the amount of food eaten is the independent variable, what is the dependent variable?

Back

The dependent variable would be the cost of the check.

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.

Front

How can you identify the dependent variable in a given experiment?

Back

The dependent variable can be identified as the outcome or effect that is measured in response to changes in the independent variable.

Front

What is an example of an independent variable in a study measuring the effect of study time on test scores?

Back

The independent variable would be the amount of study time.

Front

What is an example of a dependent variable in a study measuring the effect of temperature on the rate of a chemical reaction?

Back

The dependent variable would be the rate of the chemical reaction.

Front

Why is it important to control variables in an experiment?

Back

Controlling variables is important to ensure that any changes in the dependent variable are solely due to the manipulation of the independent variable.
