Front

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

Back

A control group serves as a baseline to compare the effects of the independent variable, helping to validate the experiment's results.

Front

What does it mean to 'test variables' in scientific research?

Back

Testing variables involves manipulating one or more factors in an experiment to observe their effects on the outcome.
