Historical research usually follows the qualitative approach. Please be aware, however, that there is a significant minority of historical researchers who follow the quantitative approach. Multimethod Research Multimethod research involves the use of more than one research method or approach. The goal is to use approaches with nonoverlapping weaknesses and complementary strengths. The use of multiple methods or approaches to research works the same way.
Some researchers like to conduct multimethod research in a single study.
Virtually all research literatures are multimethod, even if no single researcher uses multiple methods. That's because there will usually be some quantitative and some qualitative research studies in a research literature.
