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.
