Qualitative data spans a range of material from the descriptions of social life provided by participant observation and unstructured interviews to information from written sources. Quantitative data is usually in the form of statistics.
Questionnaires and structured interviews are typical methods used when gaining quantitative data, as the results are easily transferable to a numerical form. Qualitative data is associated with participant observation, it can include unstructured interviews, information from written sources such as diaries, autobiographies and novels, information focusing on descriptive aspects of social life, thus helping the researcher experience that portion of social life.
