Question

rving has noticed the following 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? naturalistic observation case study correlational research archival research

Answer 1

Answer:

The research method that would be able to answer the research question of Irving woould be

a Correlational Research.

Explanation:

The reason behind this is the objective of each research method. In the first place, naturalistic observation would require him to observe every study participant while he is under the influence of alcohol. In the second place, the case study would require him also to follow the events of every participant or to retrieve cases associated with it. But that would be a biased study because we wouldn't be able to measure the variables quantitatively. Archival research would be good, but he would depend on previous results that might be too old to be considered good, and they might not measure the two variables. However, if we develop correlational research we would be able to measure the two variables in real-time.
