CEVAP:

Concerning the level of analysis and unit of analysis debate, the former is related to the causes and the latter is related to the results. In other words, unit of analysis is a dependent variable while level of analysis is an independent variable. In this context, level of analysis is the framework for analysis for the issue to be analyzed. Therefore, unit of analysis is an agent or a state the political behaviors of which is to be analyzed. In particular, if state-centric approaches are presumed then in general unit of analysis is a state and its foreign policy behavior to be analyzed. On the other hand, level of analysis is related to the framework the states as units of analysis are situated in. But level of analysis might change according to theories used for the purposes of an analysis. For example, if system theories are employed as framework for analysis, then, system is regarded as the level of analysis, whereas the state itself would be the unit of analysis (See, Buzan, 1995: 199, 203-204).
