CEVAP:

Quantitative research, as part of empirical research, enables to describe populations and phenomena in a detailed tradition based on figures or data, and enables the political scientist to make propositions out of relationships between two or more variables. Observation and experimentation are the strategies that can be employed to test an assumption or a theory. Observation is the most used strategy by political scientists for international relations, or other social sciences while experimentation is not that commonly used due to its nature of testing.
