Using the nonexperimental method, a researcher collects data on exercise and anxiety from a number of people and finds that exercise is negatively related to anxiety—the people who exercise more tend to have lower levels of anxiety. What does this scenario demonstrate?

Covariation between the variables due to the fact that non experimental method enables us to observe covariation.

Explanation: covariance helps us to know the degree at which two variables varies from each other. Covariation helps us to know the degree to which two substance vary together like if a change in one leads to a greater changer in the other, no change at all or even a uniform change and if a change in one variable causes an inverse change or behind-me change( tandem or one behind the other change).it seeks to determine the the relationship between two various as per cause and effect.
