Social research is research conducted by social scientists following a systematic plan. Social research methodologies can be classified as quantitative and qualitative.
- Quantitative designs approach social phenomena through quantifiable evidence, and often rely on statistical analyses of many cases (or across intentionally designed treatments in an experiment) to create valid and reliable general claims.
- Qualitative designs emphasize understanding of social phenomena through direct observation, communication with participants, or analyses of texts, and may stress contextual subjective accuracy over generality.
Most methods contain elements of both. For example, qualitative data analysis often involves a fairly structured approach to coding raw data into systematic information and quantifying intercoder reliability. There is often a more complex relationship between "qualitative" and "quantitative" approaches than would be suggested by drawing a simple distinction between them.
