Research methods in international relations are the techniques and approaches that scholars use to study and analyze international relations phenomena. These methods can be qualitative, quantitative, or a combination of both, and they may involve the use of data from a wide range of sources, including statistical data, documents, interviews, and field observations.

One common approach to research in international relations is case study research, which involves in-depth examination of a specific event, issue, or phenomenon. This approach allows researchers to explore the context and complexity of a particular case in detail and can provide insights that are not possible with more generalizing methods.

Quantitative research methods, such as statistical analysis, are also commonly used in international relations research. These methods involve the collection and analysis of numerical data and allow researchers to identify trends and relationships and to test hypotheses.

Qualitative research methods, such as interviews and focus groups, are also commonly used in international relations research. These methods involve the collection and analysis of non-numerical data, such as words and images, and can provide insights into the perspectives, experiences, and motivations of different actors in the international system.

Overall, research methods in international relations are an important aspect of the field and are essential for producing high-quality, rigorous research that advances our understanding of international relations phenomena.
