Irving has noticed a pattern: The more alcohol people drink, the more aggressive they seem to be. Which research method is aimed at verifying a relationship between two variables?

The correlational method is the most appropriate to study these two variables.

Explanation:

In the field of research, the correlational method is defined as the search for some type of relationship between two or more variables, as well as how one can affect the other even without knowledge of which can affect the other. The correlational method is usually widely used in the field of psychology and sociology, where the study of phenomena not susceptible to manipulation because they are hypothetical constructs are studied. Some examples of these may become personality and intelligence.

In Irvin's case, he wants to know if there is a relationship between the amount of alcohol a person drinks and the increase in aggression. While it is true that several studies have found a close relationship, it is important to conduct this study to continue investigating other factors that may be present in the situation.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
