Full context:   Sociological research methods may be divided into two broad, though often supplementary, categories: Sociologists are often divided into camps of support for particular research techniques. These disputes relate to the epistemological debates at the historical core of social theory. While very different in many aspects, both qualitative and quantitative approaches involve a systematic interaction between theory and data. Quantitative methodologies hold the dominant position in sociology, especially in the United States. In the discipline's two most cited journals, quantitative articles have historically outnumbered qualitative ones by a factor of two. (Most articles published in the largest British journal, on the other hand, are qualitative.) Most textbooks on the methodology of social research are written from the quantitative perspective, and the very term "methodology" is often used synonymously with "statistics". Practically all sociology PhD programmes in the United States require training in statistical methods. The work produced by quantitative researchers is also deemed more 'trustworthy' and 'unbiased' by the general public, though this judgment continues to be challenged by antipositivists.
