Front

How does a graph represent data in an experiment?

Front

What is the difference between qualitative and quantitative data?

Back

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

Front

What is a control group in an experiment?

Back

A control group is a standard for comparison that is not exposed to the independent variable.
