Answer:
Comparative research.
Explanation:
In the methodology of social studies, Comparative research is used in order to compare particular aspects of different countries, nations, cultures, etc. The comparative approach helps to understand specific characteristics of each of the subjects of the study, American and German views on violence in this case. Some of such characteristics can become evident only as a result of comparison itself.
While conducting this comparative research you should be aware that understanding of violence might differ among Germany and America, and you need to find comparable categories for your research.
