GED Practice Test Question: Science

This GED Practice Test science question comes from the Scientific Reasoning section of our GED Online Course. This science lesson breaks down how to design an experiment and the scientific method.

The correct answer is the variables exhibit an indirect correlation.

Scientists tend to observe cause-and-effect relationships. These relationships can be quantified using correlations. Correlations measure the amount of linear association between two variables.

As one variable increases, the other decreases. The opposite is true if one variable decreases. A negative correlation is also known as an inverse correlation or an indirect correlation.
