To ensure that any changes in the dependent variable can be directly attributed to the independent variable being tested.

Front

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

Back

To provide a baseline for comparison, allowing researchers to see the effect of the independent variable.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.
