What is a dependent variable?

Front

What is the purpose of identifying variables in an experiment?

Back

To understand how changes in one factor affect another, allowing for clear conclusions.

Front

How do you determine the dependent variable in a question?

Back

Look for what is being measured or observed as a result of changes in the independent variable.

Front

What is a controlled variable?

Back

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

Front

Why is it important to have a control group in an experiment?

Back

A control group provides a baseline for comparison, helping to isolate the effects of the independent variable.
