I'm currently writing my qualitative doctoral dissertation and I'm not quite sure how many extracts do I need to analyse? Are 30-40 extracts enough for a dissertation?
The number of data extracts required can vary depending on the research question being addressed, the complexity of the data, the methodological approach used, and other factors. It may be best to consult with your dissertation advisor or committee members for guidance on selecting an appropriate number of data extracts to analyze and to ensure that your dissertation meets the requirements of your program. Additionally, you may find it helpful to review previous qualitative dissertations in your field to get an idea of the number of data extracts they used and how they analyzed them.
the number of data extracts depend on the data saturation, if you reach what you need from the data you will reach the saturation. This depend on your research question, research methodology. You may start analyse the extract and then continue data collection, because the data analysis and data collection is concurrent in qualitative research , you continue to collect data until you feel that you reach the data saturation , so no specific number is required. however, it is usually a small number
In principle, in qualitative research, the number of samples is not determined at the beginning of the study. You need to start the sampling process based on your research questions. When you reach data saturation, i.e. no new codes of samples are obtained, you can claim that the number of samples is sufficient. Of course, the sufficient number of samples to reach data saturation also depends on the skill of the qualitative research type researcher, but usually a large number is not required. Consider the items of precision and accuracy of qualitative study. Good luck.
That depends on the method of data collection you intends to use. If you intend using in-depth interview 30-40 is enough, on the other hand if you are using focus group 6-12 is enough
