Qualitative Data: Data are pieces of information systematically collected from a group of people. Qualitative data are words, sounds or images – not numbers. You cannot do math with qualitative data. Qualitative data are time-consuming to analyze but yield rich information that can support or explain the results of quantitative survey data. Although they are typically collected in interviews and focus groups, qualitative data can also be found in records such as student files at schools or journals kept by study participants. The best evaluations incorporate both quantitative and qualitative data.
