<Li> Quantitative designs approach social phenomena through quantifiable evidence, and often rely on statistical analysis of many cases (or across intentionally designed treatments in an experiment) to create valid and reliable general claims </Li> <Li> Qualitative designs emphasize understanding of social phenomena through direct observation, communication with participants, or analysis of texts, and may stress contextual and subjective accuracy over generality </Li> <P> Many sociologists are 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 greater public, though this judgment continues to be challenged by antipositivists . </P> <P> The choice of method often depends largely on what the researcher intends to investigate . For example, a researcher concerned with drawing a statistical generalization across an entire population may administer a survey questionnaire to a representative sample population . By contrast, a researcher who seeks full contextual understanding of an individual's social actions may choose ethnographic participant observation or open - ended interviews . Studies will commonly combine, or' triangulate', quantitative and qualitative methods as part of a' multi-strategy' design . For instance, a quantitative study may be performed to gain statistical patterns or a target sample, and then combined with a qualitative interview to determine the play of agency . </P>
