Data saturation

Monday, November 25th, 2013

Theoretical saturation of data is a term in qualitative research, mostly used in the grounded theory approach. Theoretical saturation of data means that researchers reach a point in their analysis of data that sampling more data will not lead to more information related to their research questions.(1) No additional data can be found to develop new properties of categories and the relationships between the categories are disentangled. Researchers see in their data similar instances over and over again and that make them empirically confident that their categories are saturated, the descriptions of these categories are thick and a theory can emerge. Researchers are allowed to stop sampling data and to round off their analysis. read more
