Front

What is a dependent variable?

Back

The dependent variable is the variable that is measured and affected in an experiment. It changes in response to the independent variable.

Front

In the equation y = mx + b, which variable is independent?

Back

Back

y is the dependent variable.

Front

What does it mean when we say a variable is 'controlled'?

Back

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

Front

Can the independent variable be anything we want it to be?

Back

Yes, the independent variable can be chosen based on the experiment's design.

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 study about plant growth.

Back

Front

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

Back

The height of the plants after a certain period.

Front

What is the purpose of identifying independent and dependent variables in an experiment?

Back

To understand how changes in one variable affect another.
