Give an example of a real-world scenario involving independent and dependent variables.

Back

When studying the effect of study time on test scores, study time is the independent variable and test scores are the dependent variable.

Front

What is a controlled experiment?

Back

A controlled experiment is one where all variables are kept constant except for the independent variable.
